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 yet 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. 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.' Īlong with bisexuality and heterosexuality, homosexuality is one of the three main categories of sexual orientation within the heterosexual–homosexual continuum. As a sexual orientation, homosexuality is 'an enduring pattern of emotional, romantic, and/or sexual attractions' to people of the same sex. Homosexuality is romantic attraction, sexual attraction, or sexual behavior between members of the same sex or gender.
