I know a Psychologist who did studies at the University of Mississippi in which he offered men who wanted sex changes the surgery, done by the school, for free if they would let him "mold" them for six months. He took femmy men, trained them to talk in what would be considered a more masculine way, walk in a more masculine way... just be more manly. Their testosterone levels went up significantly, most of them decided they were straight, and not one had the surgery.
Wasn't there a study years back where they found that female zebra finches are more attracted to males that have little fluorescent feathers glued to their heads?
