Coming out is the term used to describe the process of and the extent to which one identifies oneself as lesbian, gay or bisexual. There are two parts to this process: coming out to oneself and coming out to others. Coming out to oneself is perhaps the first step toward a positive understanding of one's orientation. It includes the realization that one is homosexual or bisexual and accepting that fact and deciding what to do about it.

Coming out to others is an experience unique to gay, and lesbian and bisexual individuals. The decision to come out to another person involves disclosing one's sexual side, which is for the most part viewed as being a private matter. Some are afraid of being rejected but others worry that their sexual identity will be the overriding focus in future interactions with the other person. While coming out often does result in negative consequences, it frequently leads to a sense of relief and increased feelings of closeness. Other issues are the extent of the revelation (should everyone know or should disclosure be selective?), timing and anticipation consequences.

Our culture tends to assume heterosexuality and persons who do not correct the heterosexual assumption are sometimes said to be "passing" as heterosexuals. College students may believe that passing is preferable in an environment like college, which is built on heterosexual events. These students usually experience some conflict as they make decisions on when to "pass" and when to be open and some live with fear about their secret being revealed. These students may also experience some hostility from those who are open and feel that they are not being honest with themselves or others.
