I believe it's mostly a male dominance thing, like why women had to wear hats in churches and be overly clothed; they were "bad"/temptresses, it wasn't the man's fault, he can't help but be a man and want to mate. Women don't have those urges, don't you know. When was the last time you heard of a gigolo/male prostitute being arrested? Some men are violent toward gay men and not much nicer toward women taking control of their own sexuality either.
