Self-identified heterosexual, homosexual, and bisexual male participants watched three videos--an introductory neutral (relaxing) clip and two sexually explicit films featuring two men having sex with each other and then two women with each other. The participants pressed on a lever to self-report their arousal while equipment measured their penile erection. The study reports no indication of a bisexual pattern of genital arousal, although the bisexual men did report a distinctly bisexual pattern of subjective arousal. "Male bisexuality is not simply the sum of, or the intermediate between, heterosexual and homosexual orientation," the study concludes. "Indeed, with respect to sexual arousal and attraction, it remains to be shown that male bisexuality exists."
