The term heterosexual was coined alongside the word homosexual by Karl Maria Kertbeny in 1869. The current use of the term heterosexual has its roots in the broader 19th century tradition of personality taxonomy. Hetero- comes from the Greek word ἕτερος, meaning "other party" or "another", used in science as a prefix meaning "different" and the Latin word for sex (that is, characteristic sex or sexual differentiation). The term heterosexual or heterosexuality is usually applied to humans, but heterosexual behavior is observed in all other mammals and in other animals, as it is necessary for sexual reproduction.
There is considerably more evidence supporting nonsocial, biological causes of sexual orientation than social ones, especially for males. Although no single theory on the cause of sexual orientation has yet gained widespread support, scientists favor biologically-based theories.
Scientists do not know the exact cause of sexual orientation, but they theorize that it is caused by a complex interplay of genetic, hormonal, and environmental influences, and do not view it as a choice. Across cultures, most people are heterosexual, and heterosexual activity is by far the most common type of sexual activity. As a sexual orientation, heterosexuality is "an enduring pattern of emotional, romantic, and/or sexual attractions" to persons of the opposite sex it "also refers to a person's sense of identity based on those attractions, related behaviors, and membership in a community of others who share those attractions." Someone who is heterosexual is commonly referred to as straight.Īlong with bisexuality and homosexuality, heterosexuality is one of the three main categories of sexual orientation within the heterosexual–homosexual continuum.
