It isn't possible to diagnose your problem without an examination, but it sounds like you have a condition called vulvar vestibular papillomatosis
(VVP). That's a mouthful of words for a condition that is really quite normal. Many otherwise healthy women have VVP, which is characterized by small, wart-like, flesh-colored bumps on the labia and around the opening of the vagina (the vestibule). VVP is not contagious, and it isn't associated with any disease, such as cancer. The main concern with VVP is its resemblance to genital warts
(not a consideration in someone who's never had sex), which makes some women and their sexual partners uncomfortable. In some women, VVP causes mild itching or burning, which can usually be addressed by wearing cotton underwear (rather than synthetic material) and avoiding tight-fitting clothing (e.g., pantyhose), panty liners, and perfumed feminine hygiene products.
Women who are extremely uncomfortable about VVP can have it removed by a dermatologist
is probably most effective).
It would be prudent to see your doctor to confirm your diagnosis; he/she can also review your options for treatment, if you decide you want to deal with this condition.
I hope that helps!
