Masturbation is the manual excitation of the sexual organs, most often to the point of orgasm. It can refer to excitation either by oneself or by another (see mutual masturbation). It is part of a larger set of activities known as autoeroticism, which also includes the use of sex toys and non-genital stimulation. There are also masturbation machines used to simulate intercourse. Masturbation and sexual intercourse are the two most common sexual practices, but they are not mutually exclusive (for example, many people find the sight of their partner masturbating highly ******). Some people are able to achieve orgasm only through masturbation and not sexual intercourse. In the animal kingdom, masturbation has been observed in many mammalian species, both in the wild and in captivity.

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/clitoris 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.
Reading or viewing pornography, or sexual fantasy, are often common adjuncts to masturbation. Masturbation activities are often ritualised. Various fetishes and paraphilias can also play a part in the masturbation ritual; potentially harmful or fatal activities include autoerotic asphyxiation and self-bondage.
Sometimes in order to achieve a larger, more pleasurable orgasm, people may masturbate to near climax, then hold off to reduce excitement for a short while and then continue again. This can be done numerous times and usually results in a more pronounced orgasm in the end.
Female
19th c. shunga print by KunisadaFemale masturbation techniques are quite numerous and perhaps more varied than those of males. They are influenced by a number of factors and personal preferences. Techniques include stroking or rubbing of the vulva, especially the clitoris, with the index and/or middle fingers. Sometimes one or more fingers may be inserted into the vagina to repeatedly stroke the frontal wall of the vagina where the g-spot is located. (Studies done by Masters & Johnson, however, have shown that only about 10% of women actually have orgasms through vaginal stimulation alone.) [citation needed] Masturbation aids such as a vibrator, dildo or Ben Wa balls can also be used to stimulate the vagina and clitoris. Many women will caress the breasts or stimulate a nipple with the free hand. Anal stimulation is also enjoyed by some because of the thousands of sensitive nerve endings located there.
Lubrication is sometimes used during masturbation, especially when penetration is involved, but this is by no means universal and many women find their natural lubrication sufficient—some even produce more lubricant alone than with a partner, though the reasons for this seem to be primarily psychological.
Women usually masturbate in the bathtub, shower and hot tub, sometimes including the use of warm running water to stimulate the clitoris. Common positions include lying on back or face down, sitting, squatting, or even standing. Lying face down, one may straddle a pillow, the corner or edge of the bed, a partner's leg or some scrunched-up clothing and "hump" the vulva and clitoris against it. Standing up, the corner of an item of furniture, or even a washing machine, can be used to stimulate the clitoris through the labia and clothing.
A vibrating duck. By de-dramatising the nature of a vibrator, this kind of toy has gained wider acceptance.Some reach orgasm merely by crossing their legs tightly and clenching the muscles in their legs, which creates pressure on the genitals. 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. Often, these mental triggers have associations with previous instances of arousal and orgasm. Some women 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
Some women and men masturbate by inserting objects into the urethra, such as urethral sounds. This practice is known as "sounding" . Sometimes other objects are used (e.g. ball point pens, glass thermometers), although this is a potentially dangerous technique which can cause injury and infection
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 technique is to simply hold the penis with a loose fist and then to move the hand up and down the shaft until orgasm is achieved. When uncircumcised, stimulation of the penis comes from the pumping of the foreskin. This gliding motion of the foreskin reduces friction. When circumcised the stimulation is from direct contact with the hand. Many massage (with some using a personal lubricant to reduce friction) the glans, the rim thereof and the frenular delta left over from the removal of the frenulum.
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 the use of an artificial vagina or simulacrum for masturbation. Many fondle their testicles, nipples or other parts of their body with the other hand while masturbating. Some may use vibrators and other sexual devices more commonly associated with female masturbation. Some use clothing, for example wrapping their penis with women's panties or stockings. The penis can even be rubbed with one's own foot. Males who can reach and stimulate their penis with their tongue or lips are said to be capable of autofellatio. Some men may taste or swallow their semen.
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.
Ejaculation of semen is sometimes controlled by wearing a condom or by ejaculating onto a tissue,The Mouth or some other item. A controversial ejaculation control technique is to put pressure on the perineum, about half way between the scrotum and the anus, just before ejaculating. This can, however, redirect semen into the bladder and the technique may 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 by withholding ejaculation. Proponents of tantric sex say that this is a learnable skill that can shorten the refractory period. Drugs, such as prolactin inhibitors, may also shorten the refractory period for a male. An example of this is the prescription drug Dostinex.
Historically, some have seen a connection between circumcision and masturbation frequency, which remains an argued topic. In a 1410-man survey in the United States in 1992, Laumann found that: "A total of 47% of circumcised men reported masturbating at least once a month vs 34% for their uncircumcised peers."
