LET US NOW CUT OFF A PIECE OF OUR BODY FOR NO APPARENT REASON!
Seriously though, having an uncircumsized penis is better. Sure it gets dirty, but only if you don't shower. Evolution gave it to us for a reason. It might be harder living uncut style. Which makes it more of a challenge. Here's a simple analogy: Both Tom and Jack have a motorcycle. But Jack, decided that a motorcycle is too hard to clean and manage, so he decided to trade it for a tricycle. However Tom, he's a real man and he doesn't mind a bit of a challenge. Plus he'd never trade his pride, or cut off its parts for reasons unknown to Man.
