I am 14 and I hope someone here can help I haven't had sex so I don't think its an std but and I thought it was just a birthmark or something but I didn't remember seeing it there so I eventually picked it off and it of course bled for a while not alot but enough that I need tissue to keep it from making a mess. But after a while I looked and it was back so I picked it off again same amount of blood. And it scabbed over but now it is a redish color and I have yet to break it for fear of making it worse. Altough when I push on it it gets smaller but goes back to normal size right away any help would be greatly appreciated.
