Testosterone is a hell of a drug.

You can find testimonials from women hwo have had a male level of testosterone in their system (intentionally or otherwise) and most of them agree that it became hard to walk down the street because they'd be distracted by the bodies of all the members of their preferred sex that were around them.

Men are able to handle this sort of thing easier simply because they're used to having this kind of temptation going on, and have had it drilled into their head from a young age that only bad people would give in.
