Dermatologist Questions Warts

What causes bumps to form on one's penis?

Ever since I was a little boy, I've had a sort of line of little white bumps ringing the rim on the head of my penis. What causes them?

It depends. Can be something internal such as comedones, skin tage, seb ker's or can be something external such as warts, or contact irritation or even an infection such as an STD
These are normal glands called fordyce spots. No treatment is needed.
