Risky sexual behavior

Risky sexual behavior is the description of the activity that will increase the probability that a person engaging in sexual activity with another person infected with a sexually transmitted infection will be infected or become pregnant, or make a partner pregnant. It can mean two similar things: the behavior itself, and the description of the partner's behavior. The behavior could be unprotected vaginal, oral, anal, or manual intercourse. The partner could be a nonexclusive partner, HIV-positive, or an intravenous drug user. Drug use is associated with risky sexual behaviors.
