Masturbation

=== Male ===

Male masturbation techniques are also influenced by a number of factors and personal preferences. Techniques may also differ between [[circumcision|circumcised]] and [[foreskin|uncircumcised]] males, as some techniques which may work for one can 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 person to person, 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 action#Function of gliding action|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 penis|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. Some men, also, enjoy [[anal sex|anal]] stimulation, with fingers or otherwise, without any prostate stimulation.

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.
