Recently I've noticed small, pin-sized bumps, appearing around the shaft and head of my penis, and occasionally just below the belly button. The bumps are painless, and nothing is secreting from my penis. I also do not exhibit any of the symptoms of herpes but I am still a little freaked out. The bumps tend to go away within a week but some seem to stay. There are probably only 5-10 bumps total.

Please help me.
