Like food, sex is an important part of our lives. From an evolutionary perspective, the reason is obvious—perpetuation of the species. Sexual behavior in humans, however, involves much more than reproduction. This section provides an overview of research that has been conducted on human sexual behavior and motivation. This section will close with a discussion of issues related to gender and sexual orientation.
Adolescent sexuality and sexual behavior
Sexual behaviour | Health Knowledge
Sexuality may be experienced and expressed in a variety of ways, including thoughts, fantasies, desires, beliefs, attitudes, values, behaviors, practices, roles, and relationships. Some researchers believe that sexual behavior is determined by genetics; however, others assert that it is largely molded by the environment. Human sexuality impacts, and is impacted by, cultural, political, legal, and philosophical aspects of life, and can interact with issues of morality, ethics, theology, spirituality, or religion.

Compulsive sexual behavior is sometimes called hypersexuality, hypersexuality disorder or sexual addiction. It's an excessive preoccupation with sexual fantasies, urges or behaviors that is difficult to control, causes you distress, or negatively affects your health, job, relationships or other parts of your life. 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.
Health-related behavior is one of the most important elements in people's health and well-being. Its importance has grown as sanitation has improved and medicine has advanced. Diseases that were once incurable or fatal can now be prevented or successfully treated, and health-related behavior has become an important component of public health.
