Worried about spots on backside penis

I have had these spots for over a year thinking they would eventually disappear. They are still there and im worried it might be something permanent. They look like the bumps at the base of my pubic hair. But they go all the way up only on the backside of my penis. Im uncomfortable with seeing a doctor. But i will if it turns out to be suspicious.

Note: i am still a virgin and have not had sexual relations yet.
