I have a little brother in high school, who seems quite proud of himself for discovering that some of the women in his weights class are only there to check out, and potentially attract, the football players.

WELL DUH! It's common knowledge (to us, anyway) that girls do this all the time, and they let other girls know; even bullied social outcasts and the women who actually DO enjoy weightlifting (or video games, or paintball, or what have you.) They're sneaky, and when people like my brother find out, it ruins things for the rest of us.

My question is this, men. Do you REALLY not know? Do you just not notice? Or... Do guys not do that sort of thing?
