On the weekend I went to my girlfriends house, and she was giving me hand, for a fair while. Then when i was sitting in bed last night and noticed a smallish (maybe 5mm) lump on the shaft of my penis, about halfway up, it's tender to the touch. We're are both virgins and haven't had oral sex yet. I'm only 17.
About 2 months ago I had a similar lump, but smaller, which was there for a little while and then was accidently popped and went away, that one was in a different place on the shaft on my penis.
Just wondering if it's something bad/dangerous. Should I see a doctor (which I would rather not), get some medical cream, or just leave it?
ANY assistant would be greatly appreciated as I'm seeing her again next weekend and don't want to freak her out.
