What Is Treatment Of Bumps On Penis?

Hi my name is brandon a while back I developed a scab on my penis that healed and pealed off like dry flakey skin. He docter said it was due to too much sex. Then a week later a bump developed in the area then a few more developed they dont look like herpes or warts. They are small, painless, itchless, pinkish and dischargeless bumps in a cluster I have not had any unprotected sex and the last time ive had sex has been 3 months
