I have many small white bumps on the base of my penile shaft that continue along the penile shaft almost to the head of my foreskin, I am uncircumcised. I've had them for as long as I can remember, probably noticed them when I was a teenager. I am now 20 years old and think maybe I should go for a check up as they seem to be accumulating. They are never itchy and have never developed into anything else.
