If your are causing excessive physical discomfort and interfering with normal activity you can consider surgery or non-surgical alternatives. You will need parental consent.
I would say it is very unlikely that a sexual partner will know, even if he/she is a plastic surgeon him or herself if you have had labiaplasty surgery.Healing along the inner labia tissue is somewhat similar to the inside of the mouth, which rarely leaves noticable scars. My personal...
Unfortunately the worst time to look at your labia is immediately after surgery.It is swollen, scary looking and will bring necessary stress. It takes weeks to months for everything to be settled after the procedure. Be patient, and know that things will continue to be better.
Good luck.
