Guys, are these HPV caused Genital Warts, or something other?

First off, I’d like to say that I am a 19 year old male. I have had sex with my first girlfriend ever (2 year relationship) with no problems. I met another girl after her, we hooked up once with her giving me head, and about 2 months after she first gave me head, we drank a little and she gave me head again, and I had fingered her that night also. About 5-6 months later, I noticed a single bump on my scrotum. It didn’t grow in size or cause any other problems. Just recently (the past month) I had noticed a bigger bump on my penis glans (tip of penis). Along with the bump on scrotum and penis glans, I noticed 2 more very small bumps on the right side of scrotum. They are flat topped, HARDLY raised, and they seem to have a "shiny/sheen" to them, almost reflective in a way. I had gone to my doctor 2 weeks ago about the bump on scrotum and penis glans, and he had said the penis glans bump was almost cyst-like, and the one on the scrotum was dried skin/irratation of some sort, very postively saying it wasnt an STD or anything of that sort. He made me an appointment for a urologist that is on the 10th of this month, can anyone give me some closure on this? If you are experienced in any way on Genital Warts/HPV, please give me advice/insight. Thank you very much. Attached is 4 photos of the spots. (no genitals showing) just the affected spot. Thank you Yahoo!
