Many men are hairy and nearly all guys have hairy asses. It comes with the chest, legs, face, and pits thing. Contrary to what the media would have you believe, I have found every woman I have slept think that having being average hairy is very masculine. I’m not a gorilla but have some moderate chest, ass, bush, and leg hair; pretty much what most men have. Having been through many years of health clubs, boarding school, and college, I can say unequivocally that plenty of men have butt hair and I’ve never had a chick think the less of it and in plenty of cases I knew the chicks who these guys were banging.
If we’re talking about ass crack hair then there’s no difference. I’ve had chicks “go there” and none have thought anything of it. FYI, many women also have some crack hair too.
Enjoy being a man and enjoy the bod hair. It’s a huge aphrodesiac. No matter what women say, they get going and they really like it. Two, that I can think of, have said, “You’re so manly,” while running their fingers through my chest hair.
So, no. Women know that guys are generally a lot hairier than they are and most find it a turn-on.
