Some laws regarding sexual activity are intended to protect one or all participants, while others are intended to proscribe behavior that has been defined as a crime. For example, a law may proscribe unprotected sex if one person knows that he or she has a sexual disease or to protect a minor; or it may proscribe non-consensual sex, or because of a relationship between the participants, etc. In general, laws may proscribe acts which are considered either sexual abuse or behavior that societies consider to be inappropriate and against the social norms. Sexual abuse is unwanted sexual contact between two or more adults or two or more minors, and, depending on laws with regard to age of consent, sexual contact between an adult and a minor.
