Sure. I advise you to stop paying attention to these bumps, since they are quite certainly a
normalNormal saline flush part of your anatomy. There is no STD I know of that looks like what you say you have, nor are petechiae a possibility, given where you say the bumps are and how long you say you've had them. Masturbation is not causing these. It would be a shame for you to avoid developing a relationship when there's no reason for that. If you need counseling to help you get past this, by all means seek it out.
Best.
