Human sexuality is the way people experience and express themselves
sexually. This involves
spiritual feelings and behaviors. Because it is a broad term, which has varied with historical contexts over time, it lacks a precise definition. The biological and physical aspects of sexuality largely concern the
human reproductive functions, including the
human sexual response cycle.
sexual orientation is their pattern of sexual interest in the opposite or same sex. Physical and emotional aspects of sexuality include bonds between individuals that are expressed through profound feelings or physical manifestations of
love, trust, and care. Social aspects deal with the effects of human society on one's sexuality, while spirituality concerns an individual's spiritual connection with others. Sexuality also affects and is affected by cultural, political, legal, philosophical,
ethical, and religious aspects of life.
Interest in sexual activity typically increases when an individual reaches
puberty. Although no single theory on the cause of sexual orientation has yet gained widespread support, there is considerably more evidence supporting nonsocial causes of sexual orientation than social ones, especially for males. Hypothesized social causes are supported by only weak evidence, distorted by numerous confounding factors. This is further supported by cross-cultural evidence, because cultures that are very tolerant of
homosexuality do not have significantly higher rates of it.
Evolutionary perspectives on human coupling, reproduction and
reproduction strategies, and
social learning theory provide further views of sexuality. Sociocultural aspects of sexuality include
historical developments and
religious beliefs. Some cultures have been described as
sexually repressive. The study of sexuality also includes human identity within social groups,
sexually transmitted infections (STIs/STDs), and
birth control methods. (
