expose them nipples!
I vote we have nipples on our men! screw the ESRB, we can take the teen rating! or mature or whatever (if nipples on a male chest give an M rating... I will be horrified how retarded our standards have become. I understand teen... well, no I don't, but I wouldn't be surprised. But I can't think of any games with shirtless men that isn't M, with exceptions of a few where the nipple was obviously, and poorly, edited out for US release)
Edit: After some searching I decided that nipples must be allowed, because this kid has them. And he's on an "E" game.
Not to mention Lunar 2 getting "teen" dispite basically full woman nudity only a few hours into it.
