All the "power of the mind" stuff is pure bullshit, both sexes have both male and female hormones, whichever is stronger deturmines your gender, and no homosexual people don't have high levels of the opposite sex's hormones. This wierd though it seems is practical and could come in handy (althoug I don't fancy the idea). Come to think of it recently a woman was told off by the police for breastfeeding in public (which is stupid if you ask me) but I wonder what the police would do if they saw a man doing it.
