Evaluate the possible reasons for sexual orientation.
Sexual orientation refers to a person’s preference for sexual relationships with individuals of the other sex (heterosexuality), one’s own sex (homosexuality), or both sexes (bisexuality). The term also increasingly refers to transgender (also transgendered) individuals, those whose behavior, appearance, and/or gender identity (the personal conception of oneself as female, male, both, or neither) departs from conventional norms. Transgendered individuals include transvestites (those who dress in the clothing of the opposite sex) and transsexuals (those whose gender identity differs from their physiological sex and who sometimes undergo a sex change). A transgender woman is a person who was born biologically as a male and becomes a woman, while a transgender man is a person who was born biologically as a woman and becomes a man. As you almost certainly know, gay is the common term now used for any homosexual individual; gay men or gays is the common term used for homosexual men, while lesbian is the common term used for homosexual women. All the types of social orientation just outlined are often collectively referred to by the shorthand LGBT(lesbian/gay/bisexual/transgender). As you almost certainly also know, the term straight is used today as a synonym for heterosexual.
