Could be hymenal fringe? (I've got that! My GP did a pap and sent me to a gyno for a second opinion. So you could check with a gyno if you wanted.)

If they're not sore, itchy, or bleeding, I wouldn't worry, even if they were warts, personally... Warts are basically harmless, with a potential for discomfort, and if there's no discomfort, then they're harmless.
