they are sebacious glands defintely, unless you have alot of unprotected sex then they might be gential warts which arent permanent and can be removed with ointments. Anyway I was worried about the same thing and went to see a doctor he told me all about and laughed at my ignorance, the swine.
Sebacious glands perfectly normal apparently acording to him, and alot of guys have them, also to my dismay theyre permanent unless you get surgery. So what can you do, eyou shouldnt worry as so many guys have them, and girls sometimes do. unless the girls in the future youre with are obsessed with the unobtainable perfect penis orget about it.
hope that helps
