The was a survey done a couple years ago that came to the conclusion that 1 out every 5 men has a bent penis. They didn't specify how much of a bend, but mine bends slightly to the left with a slight upward curve!!! It never caused me or any of my partners any problems!!
From what I've seen at spas and at glory holes, it's not uncommon at all. If a penis is soft, it's not easy to see but more evident in a hard one. I assume "bent" means a pronounced turn along the length...not just a general curve one way or the other. One of my friends who does threesomes with two guys does one that has a sharp turn up. She says it's harder to suck but it's a nice fuck. It looks odd but everyone is happy.
Maybe the original poster should have stated how significant a "bend" he was referring to?? As I previously stated, my penis has a slight curve to the left and an nice upward curve, but it's not really what I would describe as bent. I'd show you, but I don't think we're allowed to post photos here??? And yes, it's impossible to determine how much, if at all a penis is bent when it's flaccid!!
