A few months ago, I noticed a spot or two on the outside of my vagina, on my labium and urethral orifice. They look like moles and seem to be raised a bit. Since I'm a bit of a worrier and there were only two (and no other symptoms), I didn't think about it again. But today I noticed a bump (not necessarily a wart, but maybe - though I've never had warts) on the side of my labium. It's reddish and mostly skin-toned, like a slightly aggravated mosquito bite, but not a bite. It only hurts when I touch it and haven't noticed any itching. I also noticed about two or three more of the dark marks than before.

I'm 21 and haven't had any kind of sexual encounter, but there are others in my family who I live with who do, so I was wondering if it could be herpes - since I've heard, under certain circumstances, it's contagious. Or maybe a simple infection. I'm not sure and trying not to worry.
