Orgasm is marked by a feeling of sudden and intense pleasure, an abrupt increase in pulse rate and blood pressureand spasms of the pelvic muscles that cause contractions of the lower vagina in the female and contractions of the urethra and ejaculation by the male. Males and females are physiologically capable of experiencing orgasm from infancy, and children who engage in masturbation or sex play may achieve this sensation. Orgasm can occur while a person is asleep and dreaming, as well as from sexual intercourse or masturbation. Since the male responses are usually more rapidly induced, the male probably achieves orgasms more consistently during intercourse than does the female.
