Among female students, the prevalence was higher among lesbian and bisexual (5.6%) than heterosexual (3.0%) students. Among male students, the prevalence was higher among gay and bisexual (14.6%) and not sure (15.1%) than heterosexual (5.2%) students. The prevalence also was higher among heterosexual male (5.2%) than heterosexual female (3.0%) students, higher among gay and bisexual male (14.6%) than lesbian and bisexual female (5.6%) students, and higher among not sure male (15.1%) than not sure female (6.0%) students."
