Abstract
This study investigated heterosexual undergraduates' behavior with a same-sex close friend and their attitudes toward homosexuality after this friend disclosed his/her sexual orientation. The study also examined whether the heterosexual friend was regarded as a romantic love object or not. Participants were 77 male and 139 female undergraduates. Males decreased their behaviors with their close friend and adopted more positive attitudes toward gay men after they knew their friend's sexual orientation. Females decreased their behavior with their close friend more after learning that they were a romantic love object of their friend, compared to when tehy were not. Also females adopted more positive attitudes toward lesbians only after knowing they were not a romantic love object. These gender differences are discussed.
