I have just noticed that I have something odd on my vagina and I have no idea what it is. Where my clitoris is the labia 'flaps' go out at either side. Except on the one side there is just a bit of extra skin. Then a gap then the labia starts. On the other side there is no gap. What is this extra small blob of skin? It is right next to my clitoris and I think it's just appeared. Surely I would have noticed it before if it's always been there.
