I've had a medium sized bump between my vagina and butthole for about 2 days.
It hurts when it's touched but not so much when I sit down or move.
I gently wiped it with a napkin, and noticed that there was a bloodyish liquid coming from it. I have absolutely no idea what it is, it could not be anything sexually transmitted considering I am virgin and have not been with dirty guys. If someone could give me a good answer, it'd help A LOT. Please, and thank you.

So you have not been with any "dirty guys" what about nice clean guys? Have you had some foreplay, touching and the such?

But it sounds like something you should have your doctor look at and determine what it should be.
