I remember reading somewhere that pubic hair does serve a useful purpose beyond keeping you warm and its curly twisted crazy ways are necessary for it to function in the way that God intended. And the function is... (drumroll please) ... to prevent chafing. Yes, that's right; to stop your high-friction skin from causing that painful inflammed malady that can make your walk like you want your legs to be as far apart from each other as possible. That can look strange especially when your arms also want to follow suit and get that "hey, I'm trying to hug a big beachball that you can't see" look.

So there you go. I would also like to think that pubic hair has other decorative functions, otherwise why would merkins have been invented?

BTW a good liberal application of zinc cream usually gets rid of any chafing. Looks ugly, but feels damn good.
