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.
