Eh.. first all I"ve seen your pic, don"t be talking to me about being a man.. can you grow a full beard? I can, kthx.
I"m close Robin Williams if I let it go. But, I"m a pale computer geek with half irish heritage and dark, almost black, chest hair. So, it doesn"t look that good when it gets really full and I don"t tan very easily.
I trim my stomach hair more then my chest hair, though. Pretty much every girlfriend/female friend has always told me hairy stomachs aren"t exactly attractive. Hairy chests are dependent on tastes, but most are at least ok with it.
