Since there are 50 times more heterosexuals than homosexuals, I’d imagine the pro-anal-sex propaganda is meant to encourage more of it among straights. If you’re already contraceptive-minded, it makes sense in a filthy kind of way.
yes, likely true, because one of the myths was “only dirty girls do it,” so the intent was to just make anal sex period more acceptable, with the side benefit being to mitigate against disgust towards homosexual behavior.
