LOL well, it might have something to do with the fact that i don't follow sports, I'm not into 'cars', and i think kickin back watching a good movie is fun..
For you, i think it might have more to do with the fact that you don't see males sexually, but you do females..
That makes females both a potential mate, and a potential threat to any relationship your in/might get into.. makes it harder to be friends. Of course there is that "are they being friendly, or '
friendly' to me" part as well for you..
Me, i just don't like males in general.. I like females.. to quote one of my favorite authors:
"What a wonderful world it is that has girls in it!"
I've always referred to be around females.. Hell, in 4th grade i used to volunteer to hold the jump rope for the girls..
Of course i went to a catholic school that required the girls to wear skirts

And the guys in my class didn't get it when i said that to them either.. Dumb macho wannabes..
