Hi i’m fifteen and i recently noticed a hard, (the size of a pea) itchy lump in the crease of my labia majora. I don’t think it is a pimple because there is no head. It’s uncomfortably itchy but not very painful. I do shave where it is but i haven’t shaved in awhile so i am wondering if it has something to do with that? I am on my period too, not sexually active either. help if you can thank you!
