According to NSSHB, vaginal intercourse is condom-protected 25 percent of the time in the United States, and 33 percent of the time among single people in the United States. It also found that African-Americans and Hispanic-Americans have a higher rate of condom use than whites and other groups. The lowest rate of condom use is among people over age 40. One consequence of the acquired immunodeficiency syndrome (AIDS) epidemic has been to highlight the need for population-based estimates of the number of individuals engaging in sexual behaviors that place them at risk for human immunodeficiency virus (HIV) infection. This paper describes the prevalence of various sexual behaviors in a nationally representative sample of adults in the United States. Compulsive sexual behavior may involve a variety of commonly enjoyable sexual experiences. Examples include masturbation, cybersex, multiple sexual partners, use of pornography or paying for sex. When these sexual behaviors become a major focus in your life, are difficult to control, and are disruptive or harmful to you or others, they may be considered compulsive sexual behavior.
