Well, in the states, this surgery is not common. I agree that women should try to be happy with who they are.
It is just the same as having any plastic surgery. It all comes down to self esteem. if you can do something to feel better about a part of your body (any part) that makes you feel self conscious, then why not.
I personally just had vaginoplasty/labiaplasty. Friends I have discussed it with have mostly thought it was a crazy thing to do. But one of these friends had BA and another contemplating lipo.
I agree that women should try to be happy, but that isn't always as easy as it sounds.
