Frequency of sexual activity

The frequency of sexual activity of humans is determined by several parameters, and varies greatly from person to person, and within a person's lifetime.

The frequency of sexual intercourse might range from zero (sexual abstinence) for some to 15 or 20 times a week. It is generally recognized that postmenopausal women experience declines in frequency of sexual intercourse. . The average frequency of sexual intercourse for married couples is 2 to 3 times a week.

Sexual frequency often falls off in relationships when the initial period of limerence ends, and a common belief is that frequency of sexual intercourse often falls after marriage. However, recent evidence shows that 43% of married couples have sex a few times a month, as compared with 36% of cohabiting couples.
