All you ever wanted to know about human sexuality but were afraid to ask.

Interest in sexual activity typically increases when an individual reaches puberty. Opinions differ on the origins of an individual's sexual orientation and sexual behavior. Some argue that sexuality is determined by genetics; some believe it is molded by the environment, and others argue that both of these factors interact to form the individual's sexual orientation. This pertains to the nature versus nurture debate. In the former, one assumes that the features of a person innately correspond to their natural inheritance, exemplified by drives and instincts; the latter refers to the assumption that the features of a person continue to change throughout their development and nurturing, exemplified by ego ideals and formative identifications.
