>>20366711There was a study done on unconscious arousal by watching pupil dilation. For men, the kind of porn that caused the their pupils to dilate pretty consistently lined up with their stated sexual orientations, straight men were only aroused by straight porn, gay men only gay porn, and bisexual men both. But for women it was different, their pupils showed arousal to all genres of porn regardless of their stated orientation, even for lesbians watching straight or gay male porn. Most interestingly of all, the majority even showed arousal towards videos of animals mating, which wasn’t the case for the men.
