The little white bumps are pretty common and are not an STD.
The fact that you ejaculate when you have an erection probably means that you have not masturbated in quite some time, and your body is ready to get rid of some old cells, so you have a hair trigger. A strong erection, and sexual arousal probably add to an ejaculation. Where you talking about a night wet dream?
I would not jump to any conclusion that you are infected, if you have no pain, and have had NO SEXUAL CONTACT. You say you are still a virgin.
If you had had some contact, there might be some concern, but the leaky faucett you are speaking of is a constant drip, smells, and is somewhat unmistakable.
If you have any doubt, you can make an appointment, or you bring it up at your next doctor's appoint.
Assuming you mean small white bumps, no, there is no removal cure.
Otherwise, you can always try a warm (not hot) wash cloth compress to help circulation and see if your body fights it naturally.
