Obviously, I can't diagnose with you with certainty without seeing you. But it certainly does not sound as though you have warts now, or anything else. Since warts don't typically affect the head of the penis, I'm a little doubtful that they were warts before either, but after treatment and Aldara, the bumps that remain are almost certainly not warts now. Also, your dermatologist looked and didn't think they're warts. So it's time to stop thinking about them and move on. If they're that hard to see, I doubt that you need to worry that a girl will notice them, and it wouldn't matter if she did if they aren't warts....
