Human sexual behavior
Human sexual behavior or human sexual practices or human sexual activities refers to the manner in which humans experience and express their sexuality. It encompasses a wide range of activities, such as strategies to find or attract partners (mating and display behavior), interactions between individuals, physical or emotional intimacy, and sexual contact.
The term sexual activity can refer both to acts involving two or more people - as in sexual intercourse or oral sex- and to masturbation.
In some cultures sexual activity is considered acceptable only within marriage, although extramarital sex still takes place within such cultures. Some sexual activities are illegal either universally or in some countries, and some are considered against the norms of a society. For example, sexual activity with a minor is a criminal offense in many jurisdictions, as is sexual abuse of individuals in general.
