intercrural sex

ntercrural sex

Intercrural sex (from "inter-" and Latin "crura", legs), also known as femoral/interfemoral sex/intercourse, is a type of intercourse variously regarded as penetrative and non-penetrative sex, in which a male partner places his penis between the other partner's thighs (often with lubrication[1]), and thrusts to create friction.

[edit] Heterosexuality

The sex education and sexual experimentation of adolescents may feature intercrural sex in the interests of avoiding pregnancy and preserving virginity.[2][3] In 1987 the Shere Hite report on Female Sexuality found that some adult women reported being able to orgasm through stimulation of the clitoris by the penis, including via intercrural contact.[4]

[edit] Male homosexuality

Intercrural intercourse (termed diamerizein, "to do it between the thighs") was common in the Ancient Greek system of pederasty, where anal sex was considered demeaning to the receiving partner. The historian K.J. Dover wrote about this extensively in his book Greek Homosexuality (1977), from which current theories on the subject of Greek male-male sexuality are largely derived.[5] Joan Roughgarden refers to standing face-to-face intercrural intercourse as the "gay male missionary position" of ancient Greece in a section of her recent book Evolution's Rainbow that draws heavily on Dover.[6]

Intercrural sex is sometimes known as the "Princeton First-Year".[7] The term may refer to a system by which upperclassmen helped new students assimilate to university life in exchange for sexual gratification. A similar system was present at Oxford University, hence the synonym "Oxford Style". Students at both Oxford and Princeton may have been imitating homosexual practices in ancient Greece, referenced by authors such as Plato and Aristotle (see homosexuality in ancient Greece).

Intercrural intercourse has been proposed as an important part of the sexual lives of a handful of notable historical figures known or suspected to have been homosexual or bisexual. According to his biographer Richard Ellman, Oscar Wilde was introduced to intercrural sex by Robert Baldwin Ross, and it appears to have been his preferred activity, even over oral sex.[8] Shaka Zulu is speculated to have encouraged intercrural intercourse among his troops to "create intimacy and loyalty".[9] Quotes attributed to the Cynic philosophers regarding Alexander the Great, made both during and after his lifetime, seem to presume intercrural intercourse between Alexander and Hephaestion.[10] Similarly, comments made by a bed mate about Abraham Lincoln's thighs led to speculation of intercrural intercourse between the two in C.A. Tripp's recent The Intimate World of Abraham Lincoln.[11]

Though some modern Christians and Jews have made the argument that intercrural intercourse is not specifically condemned by Leviticus 18 or 20,[12] it has been subject to various historical sodomy laws and religious restrictions;[13] one of the questions a young man entering confessional during the medieval period would be asked was "Have you fornicated with another male between his thighs? By this I mean, have you ever put your manhood between the thighs of the other, and through vigorous movement ejaculated semen?"[14] Intercrural intercourse appears to have been common during the medieval era anyway, a contemporary document titled the "Altercatio Ganimedis et Helene" (The Debate of Helen and Ganymede) depicts Greco-Roman mythical figure Ganymede describing the "slippery thighs of a boy" as superior to the "stink and gaping looseness of the female cave".[15][16]

Intercrural sex is still quite common in some communities, a recent report on the sexual health needs of MSM in the Calcutta suburbs found that 73% of men asked engaged in intercrural intercourse, though the frequency varied based on demographic factors: only 54% of sex workers, 50% of lower income men and 40% of Muslims reported intercrural sex; while 82% of Hindus and 88% of middle income men reported engaging in it.[17] A similar study from South Asia reported that intercrural sex was tied with anal sex as the second most preferred sex act of men asked, making it more popular than oral sex or frottage.[18]

A sex toy is any object or device that is primarily used in facilitating human sexual pleasure. This term can also include BDSM apparatuses, sex furniture, sex swings, fisting sling, or angled cushions and shaped pillows. The most popular sex toys are designed to resemble human genitals and can be classified as vibrating or non-vibrating. Sex toys usually do not include contraceptives, pornography, or condoms.

A related "softer" term is adult toy. Another related term is marital aid, often used as a euphemism for sex toys, although marital aid is broader as it can also be applied to drugs and herbs marketed as supposedly enhancing or prolonging sex.

[edit] Types of sex toys

[edit] Vibrators

Vibrators are vibrating devices intended to stimulate the nerves of the body. Vibrators intended for sexual use are often dildo-shaped, although they also come in a wide range of shapes and sizes, allowing internal as well as external use.

  • Penetrative vibrators usually measure twelve to eighteen centimeters (five to seven inches) in length and two to five centimeters (one to two inches) wide to mimic the size of an actual penis. [1]
  • Anal vibrators are typically shorter than general penetrative vibrators, and have a flared base to prevent the device from becoming lodged in the rectum.
  • The G-spot vibrator is curved at the end to facilitate stimulation of the female G-spot.
  • Bullet vibrators are small, bullet-shaped vibrators that can be used for direct stimulation or inserted into other sex toys to increase stimulation.
  • Vibrator wands, such as the Hitachi Magic Wand, are large vibrators that generally plug into a wall (versus operating on battery power) and are marketed as back massagers. They are typically used for clitoral stimulation.
  • The rabbit vibrator, of which there are several variations, is a popular female sex toy popularized by the television series Sex and the City[2]. It comprises an insertable shaft which often has additional functionality, such as rotation and internal beads or a thrusting action. Attached to the shaft is a vibrating clitoral stimulator. For most rabbit vibrators this comes in the form of "bunny ears" which sit either side of the clitoris.

[edit] Penile toys

A penis sleeve
A penis sleeve
  • "Pocket pussies" or "vaginas" or "masturbators" are modelled to accept a penis for simulated intercourse. They can be shaped like vaginas, anuses, or anything with a hole for penetration.
  • Cock rings in their most basic form enhance and prolong a man's erection by keeping blood inside the penis. A man may wear a cock ring because he has erectile difficulties, or because he likes the particular sensation of tightness and engorgement that wearing one provides. Some models include a protruding clitoral stimulator, designed to stimulate the clitoris during sex. Others vibrate, either vibrating the ring itself, or in a popular 'Dolphin' variant using two removable bullet vibrators to provide stimulation to the testicles and clitoris. Some cock rings have vibrators attached which can be worn to stimulate a partner during sexual intercourse, especially in the scrotum or perineum.
  • A triple crown is a cock ring that has additional rings for restraining the testicles. In orgasm, the testicles usually retract toward the body before ejaculation. A triple crown changes and intensifies the sensation of orgasm by forcing the testicles to stay away from the body.
  • A cock harness is a more elaborate harness designed to be worn around the penis and scrotum. Its intention is similar to that of a cock ring. Often associated with BDSM activities such as cock and ball torture.
  • A ball lock is an ordinary padlock fastened around the male scrotum, separating the testicles away from the penis and not removable except by key or combination.
  • A penis sleeve is a cylindrical device that is placed on the shaft of the penis, with the aim of increasing stimulation for the person being penetrated. They often have soft bumps intended to provide further stimulation.
  • A penis extension is a partially hollow device like a very short dildo, with the hollow end placed on the end of the penis, intended to increase the effective length of the penis, again for the benefit of the person being penetrated. These are generally worn with condoms to prevent them from falling off during use.
  • A docking sleeve is a cylindrical device similar to a penis sleeve, but is open at both ends, so that two men can dock.

[edit] Glass sex toys

Glass sex toys are commonly made from clear medical grade borosilicate glass (“hard glass”) of which Pyrex is a brand. This material (essentially “lead-free crystal”) is completely non-toxic and will withstand extreme temperatures as well as physical shock without compromising its structural integrity. Glass toys made of borosilicate are completely safe. A properly annealed inch thick piece of borosilicate will withstand up to 3,000 lbs of pressure and extreme heat and cold. Glass dildos are also non porous and can be sterilized to help prevent infection with reuse. These types of sex toys are not only durable, but also very visually appealing often considered by some to be works of art. Glass sex toys are a viable and long lasting alternative to the less expensive and less appealing toys on the market.

[edit] Nipple toys

  • A nipple clamp is a clamp used to stimulate the nipples by applying varying degrees of pressure.
  • Suction devices are generally either rubber or glass, fit around the nipple, and cause nipples to become more sensitive due to engorgement. Glass suction devices may use either heat or a pump to create suction.

[edit] Anal toys

  • Butt Plugs are shorter dildos intended for anal insertion. They tend to have a flared base to prevent the device from becoming lodged in the rectum.
  • Anal Beads are balls or bumps on a string or a semi-rigid wand. They are inserted into the rectum and then removed with varying speeds.
  • Prostate Massage toys are specially curved dildos that aim to stimulate the prostate.

[edit] General penetrative toys

  • A dildo is a non-vibrating device which is used for sexual stimulation of the vagina and/or anus. Dildos are generally made of silicone rubber, or occasionally more creative materials such as metals or glass. They are often made to resemble a penis.
  • A double-ended dildo is a long, usually flexible dildo with both ends designed for penetration. It allows for mutual penetration between two persons (or for double penetration of a single female, both anally and vaginally).
  • Ben Wa balls are hollow metal balls inserted vaginally which can be worn inside the vagina for extended periods of time. The internal rolling is said to enhance orgasms, and enable women with vaginal difficulties to reach orgasm[citation needed].
  • Kegel exercisers, also known as vaginal barbells, also known as vagina jugglers are designed to improve muscle tone in the pelvic floor, and can be used for sexual pleasure as well as enhancing vaginal response.

[edit] Flesh-like materials used in sex toys

  • Silicone is soft and lifelike, warms up quickly to body temperature, non-porous therefore easy to clean (with mild soap and water, or boiled for sterilization). Unlike jelly rubber and other porous materials, silicone can be sterilized. When using lubricants with silicone sex toys it's important that silicone or silicone based lubricants are not used to avoid damage to the toy.
  • Cyberskin, also known under other brand names, a thermal plastic elastomer (mixture of PVC and silicone), is currently the closest emulation of real skin.[citation needed] As it is porous, it cannot be sterilized completely but may be cleaned with anti-bacterial soap and water. Bacteria can build up easily in the toy and should never be used if there is a tear or hole in the cyberskin. A water based lubricant is best for Cyberskin toys.
  • Latex rubber, also called jelly rubber, is commonly used for sex toys; it is a flexible and inexpensive material allowing the user more options in size and look. While latex is commonly used and less expensive it can be allergenic to some people. Latex is very porous and it must be cleaned thoroughly (with an antibactierial and water or sex toy cleaner). Even with cleaning, it cannot be sterilized. Like Cyberskin, all usage must be discontinued if there is a tear or hole in the rubber. Most rubber toys contain pthalates, a chemical used to soften rubber (also present in household items that contain plastic, such as baby bottles), that has been proven to cause cancer in animal experiments. Due to its porousness and the presence of pthalates, it is recommended by many experts that one use a condom with each use for protection against bacterial infection or adverse effects by pthalates. Water and silicone-based lubricants can be used with Latex toys, oil-based lubricants and petroleum jelly should never be used with latex as these will disintegrate the toy.

[edit] Legal issues in the United States

In many areas, such as some U.S. Southern states, the sale of sex toys is discouraged, or outlawed completely, by laws prohibiting or regulating "obscene devices".[3] As recently as 1999, an assistant attorney general in Alabama commenting on a case involving sex toys and discussing to what end the devices are used was quoted as saying there is no "fundamental right for a person to buy a device to produce orgasm". A federal appeals court upheld Alabama's law prohibiting the sale of sex toys on Valentine's Day, 2007.[4]

It is also common practice for someone to move a motor home near a proposed sex shop[citation needed] as a means of protest to prevent the shop from opening where the law prohibits an "adult" establishment within a certain distance of a dwelling.

There are organizations that assist those who sell sex toys to stay within legal limits and provide them with news, legal updates and assistance. One such organization is the National Association for Sexual Awareness & Empowerment (NASAE)

anal-oral contact

Anal-oral contact

From Wikipedia, the free encyclopedia

(Redirected from Anilingus)
Jump to: navigation, search

A tongue performing rimming on an anus.

Anal-oral contact, also referred to as anal-oral sex, rimming, salad tossing, or analingus (from anal + -lingus), is a form of anal sex involving contact between the anus or perineum of one person and the mouth (lips) or tongue of another.

Contents

[hide]

[edit] Technique

Anilingus involves a variety of techniques to stimulate the anus including kissing, licking, and sliding the tongue in and out of the anus. Pleasure for the receiver comes from the sensitive nerve endings surrounding the anal opening, which are typically stimulated by the tongue and lips.

[edit] Health risks and prevention

There are many health problems that can result from practising unsafe rimming, because of the presence of bacteria, viruses or parasites on or in the anus or rectum. These include Hepatitis A, Hepatitis C, Hepatitis B, intestinal parasites, chlamydia, human papillomavirus (HPV), gonorrhea, herpes, and other sexually transmitted diseases.[1] Applying the mouth to the genitals immediately after applying it to the anus can inadvertently introduce the bacterium Escherichia coli ("E. coli") into the urethra, causing a urinary tract infection. HIV/AIDS is not believed to be easily transmitted through rimming, although experts assert that there is a risk of acquiring HIV from rimming.[2]

Frequent rimming with casual partners increases the health risks associated with the practice. Generally people carrying infections that may be passed on during rimming will appear healthy. If the couple knows that each of them has a healthy background, there is less risk of catching one of the serious viruses or parasites. Parasites may be in the faeces if badly cooked meat was consumed. Hepatitis A traces in feces only apply if the infected person has eaten contaminated food. Hepatitis C is rare although possible if the receiver has trace amounts of infected blood through his/her anus or faeces.

If the receiving partner has wounds or open sores on their genitals, or if the giving partner has wounds or open sores on or in their mouth, or bleeding gums, this poses an increased risk of STD transmission. Brushing the teeth, flossing, undergoing dental work, or eating crunchy foods such as potato chips relatively soon before or after performing anilingus also increases the risk of transmission, because all of these activities can cause small scratches on the inside of the lips, cheeks and palate. These wounds, even when they are microscopic, increase the chances of contracting STDs that can be transmitted orally under these conditions. Such contact can also lead to more mundane infections from common bacteria and viruses found in, around and secreted from the genital regions.

[edit] HPV and oral cancer link

In 2005, a research study at the College of Malmö in Sweden suggested that performing unprotected oral sex on a person infected with human papillomavirus (HPV) might increase the risk of an oral cancer. The study found that 36 percent of the cancer patients had HPV compared to only 1 percent of the healthy control group.[3]

Another recent study suggests a correlation between oral sex and throat cancer. It is believed that this is due to the transmission of HPV because this virus has been implicated in the majority of cervical cancers. The study concludes that people who had one to five oral sex partners in their lifetime had approximately a doubled risk of throat cancer compared with those who never engaged in this activity and those with more than five oral-sex partners had a 250% increased risk.[4]

[edit] Prevention

Owing to disease risks, many medical professionals advise the use of dental dams when performing or receiving anilingus with a partner whose STD status is unknown. A makeshift dental dam can be made out of a condom (instructions). Using a real dental dam is preferable, because real dental dams are larger, and the makeshift version may be accidentally poked with the scissors during the cutting procedure. Plastic wrap may also be used, but this is less preferable because the thickness dulls sensation. Certain kinds of plastic wrap are manufactured with tiny holes to allow venting during microwaving, which may allow transmission of pathogens.

[edit] Anal-oral contact in popular culture

  • The Howard Stern Show executive producer Gary Dell'Abate has said on numerous occasions that he enjoys oral-anal contact, both giving and receiving.[5]
  • Anal-oral contact was parodied in the movie South Park: Bigger, Longer, and Uncut. In the movie, the mothers of the boys come to Mr. Mackey's office, for the boys had been swearing in class. Mr. Mackey then gave a list of the words the boys said to Kyle's mom. She then asked "What the heck is a rim job?", in which Cartman's mom said "Why, that's when you put your legs behind your head and have someone lick your ass!", which made the others stare.
  • In Pasolini's film Salò o le 120 giornate di Sodoma, anal–oral contact features multiple times, mostly between the 'men of power'.
  • Madonna is depicted having an anal-oral contact with a man in her erotic book Sex. Illustration
  • The song "Moist Vagina" by Nirvana references oral-anal contact. A portion of the lyrics: "I've been sucking the walls of her anus, Anilingus!"
  • In the UK television programme Queer As Folk's opening episode, the act of rimming is depicted between two of the lead characters.
  • In an episode of the popular American cable television program Sex and the City, the character of Miranda Hobbes shows signs of surprise when a sexual partner performs the act on her, and later proceed to dump said partner when he asks her to return the favour.

A sexual fantasy, also called an erotic fantasy, is a deliberate fantasy or pattern of thoughts with the goal of creating or enhancing sexual feelings; it is mental imagery that an individual considers erotic. The makeup and purpose of fantasies vary: they can be long, drawn-out stories or quick mental flashes of sexual imagery; their purposes range from sexual motivations, such as sexual arousal and reaching orgasm, to simply passing time or helping a person fall asleep. Sexual fantasies are nearly universally experienced and can be positive, negative, or both. A person may not wish to enact their sexual fantasies in real life; some would find their fantasies completely unacceptable — or physically impossible — were they transposed into real life.

[edit] Content and uses of fantasy

The content and goal of a sexual fantasy vary greatly between individuals and are subject to personal desires. These fantasies range from the mundane to the bizarre, and a person may have zero to full desire to carry out an imagined act; people often use fantasy to help plan out future sexual encounters.[1] Fantasies occur in all individuals and at any time of the day, although it has been suggested that fantasies are more common among frequent daydreamers.[2] Fantasies are frequently used to escape real-life sexual restraints and to imagine dangerous or illegal scenarios, such as rape, castration, or kidnapping.[3] They allow people to imagine themselves in roles they do not normally have, such as power, innocence, and guilt.[4] Fantasies present enormous influence over sexual behaviour (hence the phrase "the brain is the largest sex organ"), and can be the sole cause of an orgasm.[5] While there are several common themes in fantasies, any object or act can be eroticized.[6]

Sexual fantasy is frequent during masturbation,[7] although this is more true for men than for women.[8]

During sexual contact, some people use their fantasies to "turn off" undesirable aspects of an act[9] For example, a woman receiving cunnilingus may shut out thoughts about her body's odours or fluids in order to fantasize about her physical or emotional pleasure. Conversely, a person may use fantasy to focus and maintain arousal, such as a man receiving fellatio ignoring a distraction.[10] Men tend to be aware of only parts of themselves during sex— they are more likely to focus on the physical stimulation of one area, and as such, do not see themselves as a "whole."[11]

Many couples share their fantasies to feel closer and gain more intimacy and trust, or simply to become more aroused or effect a more powerful physical response.[12] Some couples share fantasies as a form of outercourse;[13] this has been offered as an explanation for the rise of BDSM during the 1980s— in order to avoid contracting HIV, people turned to BDSM as a safe outlet for sexual fantasy.[14]

[edit] Common fantasies

Although fantasies are generally varied, patterns have shown up in demographics, and theories have been developed to explain the results. For example, evolutionary theorists have conjectured that women may be more likely to fantasize about familiar lovers because of the imagery of a protective relationship; however, this suggestion is not consistent with findings of the actual fantasies of married women.[15] Sexual fantasies vary by gender, age, sexual orientation, and society; because of reliance on retrospective recall, response bias and taboo, there is an inherent difficulty in measuring the frequency of types of fantasies.[16] In general, the most common fantasies for men and women are: reliving an exciting sexual experience, imagining sex with a current partner, and imagining sex with a different partner. There is no consistent difference in the popularity of these three categories of fantasies.[17] The next most common fantasies involve oral sex, sex in a romantic location, sexual power or irresistibility, and forced sex.[18]

[edit] Social views of sexual fantasy

Social views on sexual fantasy (and sex in general) differ throughout the world. The privacy of a person's fantasy is influenced greatly by social conditions. Because of the taboo status of sexual fantasies in many places around the world, open discussion — or even acknowledgment — is forbidden, forcing fantasies to stay private. In more lax conditions, a person may share their fantasies with close friends, significant others, or a group of people with whom the person is comfortable.

Historically, the moral acceptance and formal study of sexual fantasy in Western culture is relatively new. Prior to their acceptance, sexual fantasies were seen as evil or sinful, and they were commonly seen as horrid thoughts planted into the minds of people by "agents of the devil."[19] Even when psychologists were willing to accept and study fantasies, they showed little understanding and went so far as to diagnose sexual fantasies in females as a sign of hysteria.[20] Prior to the early twentieth century, many experts viewed sexual fantasy (particularly in females) as abnormal. Over several decades, sexual fantasies became more acceptable as notable works and compilations, such as Alfred Kinsey's Kinsey Reports, Erotic Fantasies: A Study of the Sexual Imagination by Drs. Phyllis and Eberhard Kronhausen, and Nancy Friday's My Secret Garden, were published.[21]

Despite the Western World's relatively lax attitudes towards sexual fantasy, many people still feel shame and guilt about their fantasies. This type of shame regularly leads to a decline in the quality of a couple's sex life,[22] and an unhappy relationship.[23]

Masturbation refers to sexual stimulation, especially of one's own genitals and often to the point of orgasm, which is performed manually, by other types of bodily contact (except for sexual intercourse), by use of objects or tools, or by some combination of these methods.[1] Masturbation is the most common form of autoeroticism, and the two words are often used as synonyms, although masturbation with a partner (mutual masturbation) is also common. Animal masturbation has been observed in many species, both in the wild and in captivity.

Etymology

Look up masturbation in Wiktionary, the free dictionary.

The word masturbation is believed to derive from either the Greek word mezea (μεζεα, "penises") or the Latin manus ("hand") and the Latin turbare ("to disturb").[2] A competing etymology based on the Latin manu stuprare ("to defile with the hand") is said by the Oxford English Dictionary to be an "old conjecture". The esoteric and little-used synonym manustupration is similarly derived from manus stuprare.

While "masturbation" is the medical term for this practice, many other terms and expressions are in common use. "Onanism" is a term with religious roots. In the vernacular, terms such as "pleasuring oneself", "wanking", and "jerking off" are common. See masturbate in Wikisaurus for many others.

Masturbation techniques

Ways of masturbating common to members of both sexes include pressing or rubbing the genital area, either with the fingers or against an object such as a pillow; inserting fingers or an object into the anus (see anal masturbation); and stimulating the penis or vulva with electric vibrators, which may also be inserted into the vagina or anus. Members of both sexes may also enjoy touching, rubbing, or pinching the nipples or other erogenous zones while masturbating. Both sexes sometimes apply lubricating substances to intensify sensation.

Reading or viewing pornography, or sexual fantasy, are often common adjuncts to masturbation. Often people will call upon memories during masturbation. Masturbation activities are often ritualised. Various fetishes and paraphilias can also play a part in the masturbation ritual. Some potentially harmful or fatal activities include autoerotic asphyxiation and self-bondage.

Some people get sexual pleasure by inserting objects into the urethra (the tube through which urine and, in men, semen, flows).[5] If these objects are urethral sounds, the practice is known as "sounding".[6] Other objects such as ball point pens and thermometers are sometimes used, although this practice can lead to injury and/or infection.[7] Some people masturbate by using machines that simulate intercourse.

Men and women may masturbate until they are close to orgasm, stop for a while to reduce excitement, and then resume masturbating. They may repeat this cycle multiple times. This "stop and go" build up can achieve even stronger orgasms. Rarely, people quit stimulation just before orgasm to retain the heightened energy that normally comes down after orgasm[8] due to the release of prolactin hormone. Doing this could lead to temporary discomfort due to pelvic congestion.

Austrian psychoanalyst Wilhelm Reich in his 1922 essay Concerning Specific Forms of Masturbation tried to identify healthy and unhealthy forms of masturbation. He tried to relate the way people masturbated to their degree of inclination towards the opposite sex and to their psycho-sexual pathologies.

Female

Female masturbation techniques include a woman stroking or rubbing her vulva, especially her clitoris, with her index and/or middle fingers. Sometimes one or more fingers may be inserted into her vagina to repeatedly stroke the frontal wall of her vagina where her g-spot is located.[9] Masturbation aids such as a vibrator, dildo or Ben Wa balls can also be used to stimulate the vagina and clitoris. Many women caress their breasts or stimulate a nipple with the free hand, if these are receptive areas for sexual stimulation. Anal stimulation is also enjoyed by some. Lubrication is sometimes used during masturbation, especially when penetration is involved, but this is not universal and many women find their natural lubrication sufficient.

Common positions include lying on back or face down, sitting, squatting, kneeling or standing. In a bath or shower a female may direct tap water at her clitoris and vulva. Lying face down one may use the hands, one may straddle a pillow, the corner or edge of the bed, a partner's leg or some scrunched-up clothing and "hump" her vulva and clitoris against it. Standing up, a chair, the corner of an item of furniture or even a washing machine can be used to stimulate her clitoris through her labia and clothing.

In the 1920s, Havelock Ellis reported that turn-of-the-century seamstresses using treadle-operated sewing machines could achieve orgasm by sitting near the edge of their chairs.[10]

Women can sexually stimulate themselves by crossing their legs tightly and clenching the muscles in their legs, creating pressure on the genitals. This can potentially be done in public without observers noticing. Some masturbate using only pressure applied to the clitoris without direct contact, for example by pressing the palm or ball of the hand against underwear or other clothing.

Thoughts, fantasies and memories of previous instances of arousal and orgasm can produce sexual arousal. Some women even claim to be able to orgasm spontaneously by force of will alone, but that ability, if it exists at all, may not strictly qualify as masturbation as no physical stimulus is involved.[11][12]

Sex therapists will sometimes recommend that female patients take time to masturbate to orgasm, especially if they have not done so before.[13][14]

Male

Male masturbation techniques are also influenced by a number of factors and personal preferences. Techniques may also differ between circumcised and uncircumcised males, as some techniques which may work for one can often be quite painful for the other.

The most common male masturbation technique is simply to hold the penis with a loose fist and then to move the hand up and down the shaft until orgasm and ejaculation take place. The speed of the hand motion will vary from male to male, although it is not uncommon for the speed to increase as ejaculation nears and for it to decrease during the ejaculation itself. When uncircumcised, stimulation of the penis in this way comes from the "pumping" of the foreskin. This gliding motion of the foreskin reduces friction. When circumcised, there is more direct contact between the hand and the glans, thus a personal lubricant is sometimes used to reduce friction. Sometimes, if too much pressure is applied, it may be rubbed sore for a time.

Circumcised or not, men may rub or massage the glans, the rim of the glans, and the frenular delta.

Another technique is to place just the index finger and thumb around the penis about halfway along the penis and move the skin up and down. A variation on this is to place the fingers and thumb on the penis as if playing a flute, and then shuttle them back and forth. Another common technique is to lie face down on a comfortable surface such as a mattress or pillow and rub the penis against it until orgasm is achieved. This technique may include the use of a simulacrum, or artificial vagina.

There are many other variations on male masturbation techniques. Some men place both hands directly on their penis during masturbation, while others use their free hand to fondle their testicles, nipples, or other parts of their body. Some may keep their hand stationary while pumping into it with pelvic thrusts in order to simulate the motions of sexual intercourse. Others may also use vibrators and other sexual devices more commonly associated with female masturbation. A few extremely flexible males can reach and stimulate their penis with their tongue or lips, and so perform autofellatio.

The prostate gland is one of the organs that contributes fluid to semen. As the prostate is touch-sensitive, some directly stimulate it using a well-lubricated finger or dildo inserted through the anus into the rectum. Stimulating the prostate from outside, via pressure on the perineum, can be pleasurable as well. Semen is sometimes ejaculated onto a tissue or some other item.

A somewhat controversial ejaculation control technique is to put pressure on the perineum, about halfway between the scrotum and the anus, just before ejaculating. This can, however, redirect semen into the bladder (referred to as retrograde ejaculation). If repeated on a regular basis, this technique could cause long term damage due to the pressure put on the nerves and blood vessels in the perineum. A dry orgasm is one that is reached while withholding ejaculation (or where retrograde ejaculation has taken place). Proponents of dry orgasm say that this is a learnable skill that can shorten the refractory period.

Mutual masturbation

Main article: Mutual masturbation

Mutual masturbation is a sexual act where two or more people stimulate themselves or one another sexually, usually with the hands.

This may be done in situations where the participants do not feel physically able (or that it is socially appropriate)or people are not ready to have full sexual intercourse, but still wish to have a mutual sexual act. It is also done as part of the full repertoire of sexual intercourse, where it may be used as an interlude, a form of foreplay or simply as an alternative activity to penetration. In some people, it is the primary sexual activity of choice above all others because it enables the individuals to see face to face and leaves the hands free to caress, as seen in frottage.

Mutual masturbation can be practiced by people of all sexual orientations. If used as an alternative to penile-vaginal penetration, the aim may be to preserve virginity or to prevent pregnancy. Some people may choose it as it achieves sexual satisfaction without actual sex, possibly seeing it as an alternative to casual sex.

Masturbation frequency, age and sex

Frequency of masturbation is determined by many factors, e.g., one's resistance to sexual tension, hormone levels influencing sexual arousal, sexual habits, peer influences, health and one's attitude to masturbation formed by culture.[15] Medical causes have also been associated with masturbation.[16][17][18]

Different studies have found that masturbation is frequent in humans. Alfred Kinsey's studies have shown that 92% of men and 62% of women have masturbated during lifespan.[12] Similar results have been found in British national probability survey. It was found that 95% of men and 71% of woman masturbated at some point in their lives. 73% of men and 37% of woman reported masturbating in the four weeks before their interview, while 53% of men and 18% of woman reported masturbating in previous seven days.[19]

"Forty-eight female college students were asked to complete a sexual attitudes questionnaire in which a frequency of masturbation scale was embedded. Twenty-four of the women (the experimental group) then individually viewed an explicit modeling film involving female masturbation. One month later, all subjects again completed the same questionnaire. Subjects in the experimental group also completed a questionnaire evaluating aspects of the film. Results indicated that the experimental group reported a significant increase in the average monthly frequency of masturbation, as compared to the control group. This same group, however, reported that the film had no effect on sexual attitudes or behavior."

A 2004 survey by Toronto magazine NOW was answered by an unspecified number of thousands.[20] The results show that an overwhelming majority of the males – 81% – began masturbating between the ages of 10 and 15. Among females, the same figure was a more modest majority of 55%. (Note that surveys on sexual practices are prone to self-selection bias.) It is not uncommon however to begin much earlier, and this is more frequent among females: 18% had begun by the time they turned 10, and 6% already by the time they turned 6. Being the main outlet of child sexuality, masturbation has been observed in very young children. In the book Human Sexuality: Diversity in Contemporary America, by Strong, Devault and Sayad, the authors point out, "A baby boy may laugh in his crib while playing with his erect penis (although he does not ejaculate). Baby girls sometimes move their bodies rhythmically, almost violently, appearing to experience orgasm."

A Canadian survey of Now magazine readers (cited above), has it that the frequency of masturbation declines after the age of 17. Many males masturbate daily, or even more frequently, well into their 20s and sometimes far beyond. This decline is more drastic among females, and more gradual among males. While females aged 13–17 masturbated almost once a day on average (and almost as often as their male peers), adult women only masturbated 8–9 times a month, compared to the 18–22 among men. Adolescent youths report being able to masturbate to ejaculation around six times per day, though some men in older middle age report being hard pressed to ejaculate even once per day. On the other hand healthy 21-28 year old males are able to masturbate at least 8-10 times per day if they are not stressed. The survey does not give a full demographic breakdown of respondents, however, and the sexual history of respondents to this poll, who are readers of an urban Toronto lifestyle magazine, may not extend to the general population.

It appears that females are less likely to masturbate while in a heterosexual relationship than men. Popular belief asserts that individuals of either sex who are not in sexually active relationships tend to masturbate more frequently than those who are; however, much of the time this is not true as masturbation alone or with a partner is often a feature of a relationship. Contrary to conventional wisdom, several studies actually reveal a positive correlation between the frequency of masturbation and the frequency of intercourse. One study reported a significantly higher rate of masturbation in gay men and women who were in a relationship.[21][19][22][23]

Among some cultures, such as the Hopi in Arizona, the Wogeno in Oceania, and the Dahomeans and Namu of Africa, masturbation is encouraged, including regular masturbation between males. In certain Melanesian communities this is expected between older and younger boys. One interesting twist is the Sambia tribe of New Guinea. This tribe has rituals and rites of passage surrounding manhood which involve frequent ejaculation through fellatio. Semen is valued and masturbation is seen as a waste of semen and is therefore frowned upon even though frequent ejaculation is encouraged. The capacity and need to ejaculate is nurtured for years from an early age through fellatio so that it can be consumed rather than wasted. Semen is ingested for strength and is considered in the same line as mothers' milk.[24]

Other cultures have rites of passage into manhood that culminate in the first ejaculation of a male, usually by the hands of a tribal elder. In some tribes such as the Agta, Philippines, stimulation of the genitals is encouraged from an early age.[25] Upon puberty, the young male is then paired off with a "wise elder" or "witch doctor" who uses masturbation to build his ability to ejaculate in preparation for a ceremony. The ceremony culminates in a public ejaculation before a celebration. The ejaculate is saved in a wad of animal skin and worn later to help conceive children. In this and other tribes, the measure of manhood is actually associated more with the amount of ejaculate and his need than penis size. Frequent ejaculation through masturbation from an early age fosters frequent ejaculation well into adulthood.[26]

Masturbation is becoming accepted as a healthy practice and safe method for sharing pleasure without some of the dangers that can accompany intercourse. It is socially accepted and even celebrated in certain circles. Group masturbation events can be easily found online. Masturbation marathons are yearly events and are occurring across the globe. These events provide a supportive environment where masturbation can be performed openly among young and old without embarrassment. Participants talk openly with onlookers while masturbating to share techniques and describe their pleasure.[27][28]

Evolutionary purpose

Masturbation may increase fertility during intercourse.

Female masturbation alters conditions in the vagina, cervix and uterus, in ways that can alter the chances of conception from intercourse, depending on the timing of the masturbation. A woman's orgasm between one minute before and up to 45 minutes after insemination favors the chances of that sperm reaching her egg. If, for example, she has had intercourse with more than one male, such an orgasm can increase the likelihood of a pregnancy by one of them.[29][30] Female masturbation can also provide protection against cervical infections by increasing the acidity of the cervical mucus and by moving debris out of the cervix.[30]

In males, masturbation flushes out old sperm with low motility from the male's genital tract. The next ejaculate then contains more fresh sperm, which have higher chances of achieving conception during intercourse. If more than one male has intercourse with a female, the sperm with the highest motility will compete more effectively.[31][32][33]

Health and psychological effects

Benefits

The physical benefits of masturbation and having an orgasm or ejaculating creates heightened arousal while epinephrine courses through the body, producing the flushed face, shallow breath and post-climactic euphoria.[34] It is held in many mental health circles that masturbation can relieve depression, stress and lead to a higher sense of self-worth (Hurlbert & Whittaker, 1991). Masturbation can also be particularly useful in relationships where one partner wants more sex than the other – in which case masturbation provides a balancing effect and thus a more harmonious relationship.[35]

Mutual masturbation, the act by which two or more partners stimulate themselves in the presence of each other, allows a couple to reveal the "map to [their] pleasure centers". Witnessing a partner masturbate is an educational activity to find out the method a partner pleases him- or herself, allowing each partner to learn exactly how the other enjoys being touched.[36]

In 2003, an Australian research team led by Graham Giles of The Cancer Council Australia[37] concluded that frequent masturbation by males appears to help prevent the development of prostate cancer. The study also indicated that this would be more helpful than ejaculation through sexual intercourse because intercourse can transmit diseases that may increase the risk of cancer instead. Also, frequent ejaculation is more easily obtained and sustained over time with the aid of masturbation.

A study published in 1997 found an inverse association between death from coronary heart disease and frequency of orgasm even given the risk that myocardial ischaemia and myocardial infarction can be triggered by sexual activity. Excerpt, "The association between frequency or orgasm and all cause mortality was also examined using the midpoint of each response category recoded as number of orgasms per year. The age adjusted odds ratio for an increase of 100 orgasms per year was 0.64 (0.44 to 0.95)." That is, a difference between any two subjects appeared when one subject ejaculated at around two or more more times per week than the other. Assuming a broad range average of between 3 to 5 ejaculations per week for a healthy males, this would mean 5 to 7 ejaculations per week. This is consistent with a 2003 Australia article on the benefits against prostate cancer.[38]

Masturbation is also seen as a sexual technique that protects individuals from the risk of contracting sexually transmitted diseases. Support for such a view, and for making it part of the American sex education curriculum, led to the dismissal of US Surgeon General Joycelyn Elders during the Clinton administration.

Sexual climax, from masturbation or otherwise, leaves one in a relaxed and contented state. This is frequently followed closely by drowsiness and sleep – particularly when one masturbates in bed.

Some people actually consider masturbation as a cardiovascular workout.[39] And while doctors have no proof of this actually being true, those suffering from cardiovascular disorders (particularly those recovering from myocardial infarction, or heart attacks) should resume physical activity (including sexual intercourse and masturbation) gradually and with the frequency and rigor which their physical status will allow. This limitation can serve as encouragement to follow through with physical therapy sessions to help improve endurance.

Blood pressure

Both sex and masturbation lower blood pressure. A small study has shown that in one test group, recent full intercourse resulted in the lowest average blood pressure in stressful situations. Masturbation then led to lower blood pressure than did no recent sexual activity.[40]

Insertion

Objects inserted into the vagina or anus should be clean and of a kind that will not scratch or break. Care should be taken not to fully insert anything into the anus – any object used should have a flared or flanged base; otherwise retrieval can require medical intervention. Modern dildos and anal plugs are designed with this feature.

Pregnancy

Masturbation involving both a man and a woman (see mutual masturbation) can result in pregnancy only if semen contacts the vulva. Masturbation with a partner can also theoretically result in transmission of sexually transmitted diseases by contact with bodily fluids.

Problems for males

A man whose penis has suffered a blunt trauma or injury during intercourse may rarely sustain a penile fracture[41] or suffer from Peyronie's disease.[42] Phimosis is "a contracted foreskin (that) may cause trouble by hurting when an attempt is made to pull the foreskin back".[43] In these cases, any energetic manipulation of the penis can be problematic.

Lawrence I. Sank[44] thought that masturbating prone (lying face downward) could be responsible for sexual problems in some men including anorgasmia and erectile dysfunction. He based this theory on four men he examined and coined the term traumatic masturbatory syndrome to describe it. As of 2007, no follow-up research has been conducted and the idea is not familiar or widely-held within the medical community. Some authors, however, continue to give it credence.[45][46]

Compulsive masturbation

Masturbating frequently presents no physical, mental or emotional risk in itself,[47] but masturbation can be used to relieve boredom or stress. In either case, as with any "nervous habit", it is more helpful to consider the causes of the boredom or of the stress, rather than try to repress the masturbation.[48]

There is some discussion between professionals and other interested parties as to the existence or validity of sexual addictions. Nevertheless, there are lists of warning signs such as when sexual activity affects a person's ability to function in everyday life, or is placing them at risk, for example, of pursuing illegal or destructive activities. Very frequent and compulsive masturbation may be seen as a sign of sexual addiction.[49]

Masturbation in history and society

Antiquity

There are depictions of male masturbation in prehistoric rock paintings around the world. Most early people seem to have connected human sexuality with abundance in nature. A clay figurine of the 4th millennium BC from a temple site on the island of Malta, depicts a woman masturbating. However, in the ancient world depictions of male masturbation are far more common.

From the earliest records, ancient Sumer had a relaxed attitude toward sex, and masturbation was a popular technique for enhancing potency, either alone or with a partner.[50][51]

Male masturbation became an even more important image in ancient Egypt: when performed by a god it could be considered a creative or magical act: the god Atum was believed to have created the universe by masturbating to ejaculation, and the ebb and flow of the Nile was attributed to the frequency of his ejaculations. Egyptian pharoahs, in response to this, were at one time required to masturbate ceremonially into the Nile.[52]

The ancient Greeks had a more relaxed attitude toward masturbation than the Egyptians did, regarding the act as a normal and healthy substitute for other forms of sexual pleasure. They considered it a safety valve against destructive sexual frustration. The Greeks also dealt with female masturbation in both their art and writings. One common term used for it was anaphlan, which roughly translates as "up-fire."

Diogenes, speaking in jest, credited the god Hermes with its invention: he allegedly took pity on his son Pan, who was pining for Echo but unable to seduce her, and taught him the trick of masturbation in order to relieve his suffering. Pan in his turn taught the habit to young shepherds.[53]

Religious views

Also see Sexuality and Religion for broad coverage of this topic

Religions vary broadly in their views of masturbation, from completely impermissible[54] to encouraged as a way to achieve greater spirituality (see, for example Tantric sexuality and Taoist sexual practices).

Philosophical arguments

Immanuel Kant regarded masturbation as a violation of the moral law. In the Metaphysics of Morals (1797) he made the a posteriori argument that 'such an unnatural use of one's sexual attributes' strikes 'everyone upon his thinking of it' as 'a violation of one's duty to himself', and suggested that it was regarded as immoral even to give it its proper name (unlike the case of the similarly undutiful act of suicide). He went on, however, to acknowledge that 'it is not so easy to produce a rational demonstration of the inadmissibility of that unnatural use', but ultimately concluded that its immorality lay in the fact that 'a man gives up his personality … when he uses himself merely as a means for the gratification of an animal drive'.

Subsequent critics of masturbation tended to argue against it on more physiological grounds, however (see medical attitudes).

Medical attitudes

The first use of the word "onanism" to consistently and specifically refer to masturbation appears to be Onania, an anonymous pamphlet first distributed in London in 1716. In it was a bombastic tirade, drawing on familiar themes of sin and vice, this time in particular against the "heinous sin" of "self-pollution". After dire warnings that those who so indulged would suffer impotence, gonorrhea, epilepsy and a wasting of the faculties (included were letters and testimonials supposedly from young men ill and dying from the effects of compulsive masturbation) the pamphlet then goes on to recommend as an effective remedy a "Strengthening Tincture" at 10 shillings a bottle and a "Prolific Powder" at 12 shillings a bag, available from a local shop.

One of the many horrified by the descriptions of malady in Onania was the notable Swiss physician Samuel-Auguste Tissot. In 1760, he published L'Onanisme, his own comprehensive medical treatise on the purported ill-effects of masturbation. Citing case studies of young male masturbators amongst his patients in Lausanne, Switzerland as basis for his reasoning, Tissot argued that semen was an "essential oil" and "stimulus" that, when lost from the body in great amounts, would cause "a perceptible reduction of strength, of memory and even of reason; blurred vision, all the nervous disorders, all types of gout and rheumatism, weakening of the organs of generation, blood in the urine, disturbance of the appetite, headaches and a great number of other disorders."

Though Tissot's ideas are now considered conjectural at best, his treatise was presented as a scholarly, scientific work in a time when experimental physiology was practically nonexistent. The authority with which the work was subsequently treated – Tissot's arguments were even acknowledged and echoed by luminaries such as Kant and Voltaire – arguably turned the perception of masturbation in Western medicine over the next two centuries into that of a debilitating illness.

This continued well into the Victorian Era, where such medical censure of masturbation was in line with the widespread social conservatism and opposition to open sexual behavior common at the time.[55][56] There were recommendations to have boys' pants constructed so that the genitals could not be touched through the pockets, for schoolchildren to be seated at special desks to prevent their crossing their legs in class and for girls to be forbidden from riding horses and bicycles because the sensations these activities produce were considered too similar to masturbation. Boys and young men who nevertheless continued to indulge in the practice were branded as "weak-minded."[57] Many "remedies" were devised, including eating a bland, meatless diet. This approach was promoted by Dr. John Harvey Kellogg (inventor of corn flakes) and Rev. Sylvester Graham (inventor of Graham crackers). The medical literature of the times describes procedures for electric shock treatment, infibulation, restraining devices like chastity belts and straitjackets, cauterization or – as a last resort – wholesale surgical excision of the genitals. Routine neonatal circumcision was widely adopted in the United States and the UK at least partly because of its believed preventive effect against masturbation (see also History of male circumcision). In later decades, the more drastic of these measures were increasingly replaced with psychological techniques, such as warnings that masturbation led to blindness, hairy hands or stunted growth. Some of these persist as myths even today.

At the same time, the supposed medical condition of hysteria—from the Greek hystera or uterus—was being treated by what would now be described as medically administered or medically prescribed masturbation for women. Techniques included use of the earliest vibrators and rubbing the genitals with placebo creams.[58]

Medical attitudes toward masturbation began to change at the beginning of the 20th century when H. Havelock Ellis, in his seminal 1897 work Studies in the Psychology of Sex, questioned Tissot's premises, cheerfully named famous men of the era who masturbated and then set out to disprove (with the work of more recent physicians) each of the claimed diseases of which masturbation was purportedly the cause. "We reach the conclusion," he wrote, "that in the case of moderate masturbation in healthy, well-born individuals, no seriously pernicious results necessarily follow."

Robert Baden-Powell, the founder of The Scout Association, incorporated a passage in the 1914 edition of Scouting for Boys warning against the dangers of masturbation. This passage stated that the individual should run away from the temptation by performing physical activity which was supposed to tire the individual so that masturbation could not be performed. By 1930, however, Dr. F. W. W. Griffin, editor of The Scouter, had written in a book for Rover Scouts that the temptation to masturbate was "a quite natural stage of development" and, citing Ellis's work, held that "the effort to achieve complete abstinence was a very serious error."

The works of Sexologist Alfred Kinsey during the 1940s and 1950s insisted that masturbation was an instinctive behavior for both males and females, citing the results of Gallup Poll surveys indicating how common it was in the United States. Some critics of this theory held that his research was biased and that the Gallup Poll method was redundant for defining "natural behavior".

In 1994, when the Surgeon General of the United States, Dr. Joycelyn Elders, mentioned as an aside that it should be mentioned in school curricula that masturbation was safe and healthy, she was forced to resign,[59] with opponents asserting that she was promoting the teaching of how to masturbate. Many believe this was the result of her long history of promoting controversial viewpoints and not due solely to her public mention of masturbation. Her case led to the coining of a new and humorous slang term for masturbation: "firing the surgeon general."[60]

Law

The legal status of masturbation throughout history have varied from virtually unlimited acceptance to complete illegality. In a 1640s law code for the Puritan colony of New Haven, Connecticut in the 17th century "blasphemers, homosexuals and masturbators" were eligible for the death penalty.[61]

Masturbate-a-thon

Main article: Masturbate-a-thon

Masturbate-a-thons are public, charity events that are "intended to encourage people to explore safer sex, talk about masturbation and lift the taboos that still surround the subject."[62] May is considered "Masturbation Month" by an evolving, loosely connected group of masturbation activists, including Betty Dodson, Joani Blank, Susan Block, Kyla Zellers, Carol Queen, and Dr. Gary Francis Fanning Jr.

Euphemisms

Because masturbation is often an uncomfortable topic among peers, a huge variety of euphemisms and dysphemisms have been invented to describe it. For a complete list of terms, see the entry for masturbate in Wikisaurus.

Masturbation in other animal species

Masturbatory behavior has been documented in a very wide range of species. Individuals of some species have been known to create tools for masturbation purposes.[63]
