I have always had the really small bumps on the base of my penis. But lately some bigger skin color bumps have been arising farther up the shaft. However i have not been sexually active for atleast 5 months, they just showed up about 2-3 months ago. I am including some pictures, any help would be appreciated, until i can get to a clinic to have it checked out. The bumps do not itch or bother me at all.
