Sexual minorities experience significant stigma and prejudice. Much research has examined sexual stigma and prejudice impacting gay and lesbian individuals, but limited research has examined other sexual minorities, such as transgender persons or individuals whose gender identity or expression is incongruent with their assigned gender or anatomical sex. Research has found that interpersonal contact with sexual minorities is associated with lower sexual stigma and prejudice. Intergroup contact theory predicts that interaction between groups can reduce stereotyping and improve intergroup relationships. Using a randomized crossover design, this study compared the impact of exposure to a transgender speaker panel vs. a traditional transgender lecture presentation on transphobia. Results indicated greater immediate reductions of transphobia following the transgender speaker panel than traditional lecture.In a largely heterosexual culture, individuals who are gay, lesbian, bisexual, or transgender (GLBT) represent sexual minorities. Heterosexism, a cultural ideology that defines heterosexuality as normal and natural and devalues any deviation from a heterosexual norm, promotes and perpetuates sexual stigma or "negative regard, inferior status, and relative powerlessness that society collectively accords to any nonheterosexual behavior, identity, relationship, or community" (Herek, 2007, p. 906).Herek (2007) argued that sexual stigma can manifest in three major forms: enacted stigma, felt stigma, and internalized stigma.

Felt stigma refers to the experience of, or even the mere expectation of, enacted stigma by targets and potential targets of enacted sexual stigma. Internalized stigma refers to the incorporation of sexual stigma into one's personal value system. Among heterosexual
