I've seen a penis or 2 that was not cut and the opening on the end was kinda small, making it hard for the head to pop out.  I've seen all sorts of, what I call, FrankenCocks.  Just as every vagina is different, so is every cock.  Like MissMocha said, cleanliness is paramount.  

Sometimes though, when not cut, the part covered by skin can be too sensitive, among other things.  See a trend here with the uncut cocks?  There are too many issues that can arise.  

Also, always remember, whether you're cut or not... when you pee and shake a little, then put it in your pants without wiping the excess pee off, that shit dries up and makes your penis smelly.  So if you ever wonder why your girlfriend/wife won't go down on you, check that problem first.  Just like a mechanic. Find out where the problem is =)  

Peace!

That said, cut or uncut does not matter much to me.

Absolutely agree, it's all about keeping things clean!

A gent taking care of himself and his hygiene is far more important than whether he's "cut" or not!
