Its another unfortunate example of women being made to feel their bodies are wrong and then someone profiting.
Young women these days see examples of denuded vulvae in porn magazines. Well of course they all look neat and symmetrical don't they, with the outer labia completely covering the inner labia. Hey presto, anything else is "wrong" and needs to be put right. So they have operations to trim their inner labia. Another example of the cosmetic surgery industry benefiting from the airbrushed porn industry. Just like the boobs - i once looked at a copy of the Star and all the boobs (and there were dozens) were all identical.
Just like in the average changing room
I did once talk to a middle aged woman who had had the op, about 20 years ago, on the NHS. She was rather unhappy that the doctor did a more radical job than she expected.
