I found a lump on my vulva today. It's not massive, but much bigger than a spot, and is quite sore. It wasn't there this morning I don't think, so came up in the two hours I was out. I squeezed it (disgusting I know, but I couldn't help it) and quite a bit of pus (I think?) came out, but it's still there and still sore. What is it? Sorry for disgusting thread btw.
