== Human orgasm ==

'''=== Male''' ===

In a [[human]] male orgasm, there are rapid, rhythmic contractions of the [[prostate]], [[urethra]] and the [[muscle]]s at the base of the [[penis]], which force stored [[semen]] to be expelled through the penis's urethral opening. This is referred to as [[ejaculation]]. The process usually takes from 3 to 10 seconds. The process is usually, but not always, extremely pleasurable. Note that it is possible to ejaculate without reaching orgasm, and to have an orgasm without ejaculation. Following orgasm, a [[refractory period]] occurs during which a man cannot have another orgasm. This period can be anywhere from one minute to over half an hour, depending on the individual and his age.

'''=== Female''' ===

In a human female orgasm, orgasm is preceded by moistening of the vaginal walls, and an enlargement of the [[clitoris]] due to increased blood flow trapped in the clitoris's spongy tissue. Some women exhibit a sex flush; a reddening of the skin over much of the body due to increased blood flow to the skin. As a woman come closer to having orgasm, the clitoris moves inward under the clitoral hood, and the [[labia minora]] (minor lips) become a darker pink. As orgasm becomes imminent, the [[vagina]] decreases in size by about 30% and also becomes congested with blood. The [[uterus]] then experiences muscular contractions. A woman experiences full orgasm when her uterus, vagina and [[pelvic muscles]] undergo a series of rhythmic contractions.
