I have had these small bumps on my penis for almost 4 years shortly after my daughter was born. It started off with this dark cluster above my private area, than the bumps started showing up on the shaft. They don t itch , burn , or brother me but the dark cluster does itch occasionally and has bled before. My fiancée is worried it is a form of cancer , at least the dark cluster. Is there any insight on what they could be? They have spread over the years, but again I ve had them going on almost 4.
