If it were possible to have my vagina removed surgically (I'm sure it is), then yes I'd do it for a billion dollars. Even if I were a dude, I'd definitely remove my weiner for a billion bucks. Sex is awsome, but getting to literally be able to do every other exciting thing that the world has to offer - that definitely trumps sex.
But again, I'm a girl and money/shopping excites me in ways you gents will never understand lol.
