i have 3 hard bumps on the outer lips of my vagina. They cannot be squeezed and nothing comes out of them. They are not irritable or itchy, just hard bumps. I do shave so I know it's a possibility of an ingrown hair, however I've never had an ingrown hair quite like this. I've been with the same guy for several monthS and him and I have both been checked prior to our relationship and never had anything. What could this be?
