So honestly, I’m not super worried about this, mainly curious. I have this small (maybe about the size of a medium sized mole) black/purplish colored spot on my vaginal lips. It’s been there for a while now, maybe four or five years? It’s not raised, doesn’t hurt, and seems to be maybe a discoloration to the skin. It looks like a blood blister almost, but it’s no flat like a blood blister, it wrinkles and bends with the skin.
