hello, I have 3 small skin colored bumps on the shaft of my penis below the wrinked skin underneath the head of the penis. They are not itchy or painful, it s been 3 years since my last sexual encounter which was with protection, just noticed them this week. I saw my doctor, a year ago when i had one, which went away. My doctor told me it was normal and not to worry, but now it s returned and i have 3 of them so i m wondering if he was wrong and it is something i should be worried about.
