If this is something you think bothers you physically, meaning you can see it through your underwear, bathing suits, tight pants, etc., there is a surgery called labioplasty that can be done. (I've seen it on the show Dr. 90210 - I'd never even heard of such a thing before.)
Here's a link with information. Good luck.
