It is a cosmetic procedure. The term you're looking for is a procedure for reasons of solely vanity (and not mental health)
Feluna, the fact you mispelled red basically summed up your entire posts ignorance. It is a cosmetic surgery, and you can compare it with a boob job for some people. YOU are assuming transgender is a special issue just because it gets more lime-light.
@Narzinor, you don't just get a surgery with such treatment. If you did, that WOULD be purely vanity.
