Biphobia is a term used to describe the fear of, aversion to, or discrimination against bisexuality or LGBT people (or those perceived to be) who are bisexual or perceived to be bisexual. It can also mean hatred, hostility, disapproval of, or prejudice towards LGBT people, sexual behavior, or cultures. Biphobic is the adjective form of this term used to describe the qualities of these characteristics while the less common biophobe is the noun form given as a title to individuals with "biphobic" characteristics. It need not include or exclude homophobia or heterophobia, because there are stereotypes that are specific to bisexuals. In some cases, bisexuals are accused of bringing sexually transmitted diseases into the heterosexual community or into the LGBT community. A related stereotype is one in which a bisexual person is presumed to be willing to have sex with just about anyone. This stereotype leads to unwanted attention of a sexual nature directed at bisexual females by swingers and heterosexual males while often stereotyping bisexual males as walking AIDS risks.
