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.

Famous quotes containing the words human and/or behavior:
“Nor blame I Death, because he bare
The use of virtue out of earth;
I know transplanted human worth
Will bloom to profit, otherwhere.
For this alone on Death I wreak
The wrath that garners in my heart:
He put our lives so far apart
We cannot hear each other speak.”
—Alfred Tennyson (1809–1892)
“The confusion of emotions with behavior causes no end of unnecessary trouble to both adults and children. Behavior can be commanded; emotions can’t. An adult can put controls on a child’s behavior—at least part of the time—but how do you put controls on what a child feels? An adult can impose controls on his own behavior—if he’s grown up—but how does he order what he feels?”
—Leontine Young (20th century)
