They eventually increase in speed and intensity as the orgasm approaches, until a final "plateau" (the orgasmic) pleasure sustained for several seconds.During orgasm, a human male experiences rapid, rhythmic contractions of the anal sphincter, the prostate, and the bulbospongiosus muscles of the penis. The sperm are transmitted up the vas deferens from the testicles, into the prostate gland as well as through the seminal vesicles to produce what is known as semen. The prostate produces a secretion that forms one of the components of ejaculate. Except for in cases of a dry orgasm, contraction of the sphincter and prostate force stored semen to be expelled through the peniss urethral opening. The process takes from three to ten seconds, and produces a pleasurable feeling. Ejaculation may continue for a few seconds after the euphoric sensation gradually tapers off. It is believed that the exact feeling of "orgasm" varies from one man to another. After ejaculation, a refractory period usually occurs, during which a man cannot achieve another orgasm. This can last anywhere from less than a minute to several hours or days, depending on age and other individual factors. Females
A womans orgasm may, in some cases, last a little longer than a mans. Womens orgasms have been estimated to last, on average, approximately 20 seconds, and to consist of a series of muscular contractions in the pelvic area that includes the vagina, the uterus, and the anus.
