What are these bumps on my penis?

Hi I have had these small (2mm or less) bumps on my penis for a long time (at least 4 years) they are white or mainly the color of my skin, and go about half the way up my penis. They are much more visible when my penis is erect, and it seems like after a while hair sprouts out of these bumps. I have been doing some internet research and think they are Fordyce's spots....
