If you google the procedure, which I'm sure you have, there are risks (like with any proceudre), nerve damage in particular worries me. I have a condition called vulvar vestibulitis, thankfully I'm still able to ride, but am unable to have sex (caused by excess growth of nerves etc). Depending on how the labiaplasty is performed, it sounds like some of the same nerves could be damaged-but that depends on your specific anatomy-only a surgeon could identify the risks in your case. It sounds like you're ready to see a surgeon-they might even be able to put you in touch with women who have had the procedure.
