Hello
I have had a small, round, hard bump for a few months. About 2 weeks ago it popped on its own and was just leaking yellowish fluid. When pressed, some blood as well. It healed up and stopped leaking but is still there. It itches a bit but otherwise just irritating. Now there is another close to it. I am afraid it is an STD, but I am not sure. I have been active once in the last year.
