Though the discussion at the link just above starts out from porn, it soon moves into questions of gender, "slutty dress" and masculine/feminine self-images. The guy called "USADave" and the flat contradictions in his lines of argument - on one hand, he maintains that sexual orientations aren't much to do with your outdoor, daytime personality, it really comes to life in private; on the other he's hellbent that real men and real women are like in an old Western movie - is one of the things that make it so illuminating.
