Sexual identity and sexual behavior are connected to sexual orientation but are different. Sexual identity is a concept of self. Sexual behavior is sex with other people. Sexual orientation is connections to other people. An individual may or may not show sexual orientation from behavior. A person who is not heterosexual by sexual orientation and has a heterosexual sexual identity is 'closeted'. This term may show a stage of change in any society that, little by little, attempts to support the sexual minority. In any sexual orientation study, scientists use the terms "concordance" (sexual attraction, sexual behavior, and sexual identity match) or "discordance" (sexual attraction, sexual behavior, and sexual identity do not match)"." Here is an example of discordance. A woman with attraction to women says she is heterosexual and only has sex with men. Sexual orientation (homosexual), sexual identity (heterosexual), and sexual behavior (heterosexual) of the woman do not match.
