I have a small white bump between my vagina and my butt hole, off to the side, It s white and hollow (pimple looking) when I push on it it feels like i can feel veins in the hollowness, it doesn t hurt and I m 15 and not sexually active I also have a 1 inch long lump on the back side of the lip of my vagina, it s painful and hard. One more; I have black head looking dots near the white lump and they are not raised or painful.
