I'm very happy with my pussy... but mine is all tucked in and neat, so I don't know how I would feel if I was a hanger-outer. To be honest, I have often looked at pics of hanger-outers (in hardcore porn) and thought, gosh, I like mine the way it is... but if I had one like that, I hope I'd be just as confident about myself!
This would be like people surgically correcting outie belly-buttons to make them more "neat" and tucked in... and why don't they do that? Because it's not a directly sexual part (boobs or pussy), and men/women don't get obsessed over that part and how it looks to their prospective partner. (Personally, I would never be with someone who doesn't always think I'm hot, no matter how old we are... ktspktsp is wonderful that way, and we make jokes about our dentures bumping into each other when we are old)
I think the beauty of a person is in the "imperfections" (for lack of a better word). Who wants to fuck a manufactured piece of plastic, someone that you could find a copy of at any corner whorehouse?
