Human Sexual Behavior
Vasocongestion is essential for sexual procreation in mammals since this is the force that causes the hardening of a penis during an erection. The same force leads to the hardening of the clitoris and vaginal lubrication during sexual arousal. The decrease in vasocongestion in post-menopausal women may require some women to use artificial sexual lubricant to avoid pain during sexual intercourse.
Other forms of vasocongestion during human sexual activity include sex flush and the swelling of nipples in both men and women.
Unpleasant side effects of sex-related vasocongestion may lead to the cramp-like pain of "blue balls" in males and an unpleasant pelvic "heaviness" in women, similar to the start of the menstruation cycle.
