I don't know a whole lot about cause and affect, but it sure does seem to be normal. I have known many from both sides of the fence and haven't noticed that they are all that different. Everyone I know is different than I am, but I don't see any trends to speak of. I've known some guys who are rough and tough, but are just attracted to men. Others are more feminine like you would see from Hollywood. I also know some straight guys who are just as feminine. It seems to me that you just can't judge a book by it's cover. People is people.
