Woman masturbating, 1913 drawing by Gustav Klimt.

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 Pocket Oxford Dictionary once offered (c. 1960) the definition: 'bodily self-pollution'.^{[citation needed]} The esoteric and little-used synonym manustupration is similarly derived from manus stuprare.

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 use lubricating substances to intensify sensation. A sex organ, or primary sexual characteristic, narrowly defined, is any of those parts of the body (which are not always bodily organs according to the strict definition) which are involved in sexual reproduction and constitute the reproductive system in an complex organism; namely: Male: penis (notably the glans penis...

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 ^[3] (The urethra is the tube through which urine and, in men, semen, flows.) If these objects are urethral sounds, the practice is known as "sounding."^[4] Other objects such as ball point pens and thermometers may be used. This practice can cause injury and infection.^[5] Urethral Play (UP) is any play or activity, usually sexual in nature, that involves the insertion of toys or items into the urethra. ...

Some people 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" method is practiced in order to achieve even stronger orgasms.

Rarely, people quit stimulation just before orgasm to retain a heightened energy that normally comes down after orgasm ^[6] due to the release of prolactin hormone.

Austrian psychoanalyst Wilhelm Reich in his 1922 essay "Concerning Specific Forms of Masturbation" focused on healthy and unhealthy forms of masturbation. In it he related the posture of the person masturbating to psycho-sexual pathologies, e.g. a male who masturbates lying on the back using only his hand as the active force, he would deem an unfavourable prognosis for achieving orgastic potency. Wilhelm Reich (March 24, 1897 – November 3, 1957) was an Austrian psychiatrist and psychoanalyst. ...

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.^[7] 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.

Common positions include lying on back or face down, sitting, squatting, or even 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, the corner of an item of furniture, or even a washing machine or chair, can be used to stimulate her clitoris through her labia and clothing.

Some women can reach orgasm merely by crossing their legs tightly and clenching the muscles in their legs, which creates pressure on the genitals.^{[citation needed]} This can potentially be done in public without observers noticing. Some prefer to use 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.

A few women can orgasm spontaneously, after experiencing prior sexual arousal, due to intellectual stimulation alone, for instance listening to certain pieces of music.^{[citation needed]} Often, these mental triggers have associations with previous instances of arousal and orgasm. 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.^[9]

Sex therapists will sometimes recommend that female patients take time to masturbate to orgasm, especially if they have not done so before.^[10][11]

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. This article is about male circumcision. ...

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, the skin on the area may swell up and become painful for a time.

Another technique is to place just the index finger and thumb around the penis about halfway along the shaft 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. A less 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.

Other techniques include rubbing penis back and forth against slippery surfaces (e.g.wet toilet walls).This technique helps to achieve orgasm faster if you had sex with your partner in a toilet before. Lying in a water bath and inserting your penis into an artificial vagina is also an effective masturbation technique.

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.

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.

Ejaculation of semen is sometimes controlled by wearing a condom or by ejaculating onto a tissue or some other item. The individual male's ability to project his semen over a distance during ejaculation may also influence a male's behaviour at ejaculation, as some males on rare occasions have been known to ejaculate up to three meters (about ten feet).

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.

Masturbation frequency, age and sex

Renaissance art depicting two boys engaging in sex play (fresco, Museum of Villa Giulia, Rome).

Frequency of masturbation is determined by many factors, e.g., one's resistance to transient sexual tension, hormone levels influencing sexual arousal, sexual habits established during youth, peer influences, health, intensity of the ejaculatory urge,^[12] and one's attitude to masturbation formed by culture.^[13] Medical causes have also been associated with masturbation.^[14][15][16] Image File history File links Satirello_che_ne_masturba_un_altro_-_Roma,_Museo_di_Villa_Giulia,_foto_di_Giovanni_Dall'Orto_-_marzo_2005. ...

"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.^[17] 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." For the British publication, see NOW magazine (UK). ... Selection bias is the error of distorting a statistical analysis by pre- or post-selecting the samples. ... Child sexuality refers to sexual feelings, behavior and development in children. ... Orgasm is the conclusion of the plateau phase of the sexual response cycle, and is experienced by both males and females. ...

According to a Canadian survey of Now magazine readers cited above, the frequency of masturbation declines after the age of 17. However, most 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. It is also apparent that masturbation frequency declines with age. Adolescent youths report being able to masturbate to ejaculation six or more times per day, while men in middle age report being hard pressed to ejaculate even once per day. 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.

This may be because females are less likely to masturbate while in a heterosexual relationship than men. Both sexes occasionally engage in this activity, however, even when in sexually active relationships. 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 as well as the number multiple sex partners. One study reported a significantly higher rate of masturbation in gay men and women who were in a relationship.^{[18][19][20][21]} Heterosexuality is a sexual orientation characterized by esthetic attraction, romantic love or sexual desire exclusively for members of the opposite sex or gender, contrasted with homosexuality and distinguished from bisexuality and asexuality. ...

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.^[22]

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.^[23] 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.^[24]

Masturbation is becoming accepted as a healthy practice and safe method for sharing pleasure without the strings. It is socially accepted and even celebrated in certain circles. Group masturbation events can be found online in just about any state. Masturbation marathons are yearly events and are occurring across the globe from the U.S. to the UK. 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.^[25][26]

Evolutionary purpose

Masturbation exercises sexual functions to increase fertility during intercourse.

Masturbation in females is a tool to regulate the conditions in the vagina, cervix and uterus, which is used to either increase or decrease the chances of conception from intercourse, depending on the timing of the masturbation. This timing is a subconscious decision. If she has intercourse with more than one male, it favors the chances of one or the other male's sperm reaching her egg.^[27][28]

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.

The function of masturbation in males is to flush out old sperm with low motility from the male's genital tract. The next ejaculate contains more fresh sperm, which has higher chances of achieving conception during intercourse. If more than one male is having intercourse with a female, the sperm with the highest motility will compete more effectively.^[29][30][31] Sperm competition is competition between sperm of two or more males for the fertilization of an ovum (Parker 1970). ...

Health and psychological effects

Benefits

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.^{[citation needed]} Clinical depression (also called major depressive disorder, or unipolar depression when compared to bipolar disorder) is a state of intense sadness, melancholia or despair that has advanced to the point of being disruptive to an individuals social functioning and/or activities of daily living. ...

In 2003, an Australian research team led by Graham Giles of The Cancer Council Australia^[32] 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. The Cancer Council Australia is a national, private organization which aims to promote cancer-control policies and to reduce the illness caused by cancer in Australia. ... Prostate cancer is a disease in which cancer develops in the prostate, a gland in the male reproductive system. ... Cervical cancer is a malignancy of the cervix. ...

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. Joycelyn Elders Minnie Joycelyn Elders (born August 13, 1933) was the United States Surgeon General from September 8, 1993 to December 31, 1994, most famous for her outspokenness on sensitive issues of public health. ...

Many people see masturbation as an effective, natural cure for insomnia. 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.^{[citation needed]} This article or section does not cite any references or sources. ...

Some people actually consider masturbation as a cardiovascular workout.^[33] 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. Some doctors will advise those recovering from heart attacks to resume sexual activity (solitary or with a partner) when one is able to climb two flights of stairs without experiencing shortness of breath or chest pain.^{[citation needed]}

Blood pressure

A small study has shown that a test group which only had intercourse experienced, as a whole, lower blood pressure in stressful situations than those who had intercourse but also had masturbated for one or more days^[34].

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.

A man whose penis has suffered a blunt trauma or injury during intercourse may rarely sustain a penile fracture,^[35] or come later in life to suffer from Peyronie's disease.^[36] Phimosis is "a contracted foreskin (that) may cause trouble by hurting when an attempt is made to pull the foreskin back".^[37] In these cases, any energetic manipulation of the penis can be problematic. A penile fracture is an injury caused by the rupture of the male corpus cavernosum. ... Peyronies disease is a rare connective tissue disorder involving the growth of fibrous plaques in the soft tissue of the penis affecting as many as 1% of men. ... Phimosis is a medical condition in which the foreskin of the penis of an uncircumcised male cannot be fully retracted. ...

Lawrence I. Sank^[38] observed that masturbating prone (lying face downward) could be responsible for sexual problems in men including anorgasmia and erectile dysfunction, as observed in four men he examined. He coined the term traumatic masturbatory syndrome to describe this theory. As of 2007, no follow-up research has been conducted and the idea is not familiar or widely-held within the medical community. Some sources, however, give credence to the idea. One sex therapist^[39] condemned masturbation by rubbing against a pillow or mattress and Lipsith et al^[40] suggest that masturbation could play a part in male psychogenic sexual dysfunction (MPSD), citing Sank as their authority. MPSD is a difficulty in reaching orgasm during intercourse, and developing a dependence on masturbation.

Compulsive masturbation

Masturbating frequently presents no physical, mental or emotional risk in itself,^[41] 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.^[42]

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.^[43] Sexual addiction (sexual compulsion)—a postulated form of psychological addiction—is a hotly debated topic with numerous critics and evidence on both sides of the debate. ...

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.

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.

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.

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'. Immanuel Kant (22 April 1724 – 12 February 1804) was a German philosopher from Königsberg in East Prussia (now Kaliningrad, Russia). ...

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."

Rheumatism or Rheumatic disorder is a non-specific term for medical problems affecting the heart, bones, joints, kidney, skin and lung. ...

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.^[45][46] 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."^[47] 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.^[48] Hysteria is a diagnostic label applied to a state of mind, one of unmanageable fear or emotional excesses. ...

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". Alfred Charles Kinsey (June 23, 1894 – August 25, 1956), was an American biologist and professor of entomology and zoology who in 1947 founded the Institute for Research in Sex, Gender and Reproduction at Indiana University, now called the Kinsey Institute for Research in Sex, Gender and Reproduction. ...

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, 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."[2] 1994 (MCMXCIV) was a common year starting on Saturday of the Gregorian calendar, and was designated as the International Year of the Family and the International Year of the Sport and the Olympic Ideal by United Nations. ...
