Jag, I have to disagree with you on this one. It's simple: women like to be ogled by boys who they deem as being cute, handsome, hot, goodlooking, sexy, whatever. The ones who aren't just don't have the same privileges. Women don't want to admit it, but we have a bit of narcissism deep within us, and we like to be noticed for our looks...but only by the right guy.
And I do stare at a man's body: face, arms, crotch, butt, chest, everything. That is, if I'm interested. If I'm not and I don't want any attention from that guy, then I do everything to ignore him and go nowhere near him.
It all comes down to who and what we're attracted to. That is a huge force dictating our actions and reactions towards the opposite sex.
