Watch any movie where there's a scene of a guy getting nailed in the crotch. There will always be a simultaneous "Oooooooo" from the audience, take note of the pitch from that cringing noise; it's not in the key of a womanly voice. Oh no, its in the baritone pitch that most men have. That laughter you hear? That's coming from the women in the audience; go ahead pay attention to your girlfriend's reaction the next time you take her to a romantic comedy and the male interest is dealt a crotch shot.
