I think I might have a STD?

Ok, so when I was little I never pulled back my foreskin, and when I pissed...it came in contacted with the foreskin. So i 6th grade, I finally pulled it back. I came to realize that I had these like white looking bumps on my head and the penis was red. Later on I looked more closely and I found there were little bumps around my penis and balls...they aren't white, just bumps that are my skin color. So I'm 18 now, never had sex, and I just recently found I have some bumps under my eyes, they very small. And I found out I have bump looking things on my lips, tongue, and possibly in my throat. I've been doing research to see if this is an STD, which I pray to God it isn't or it's Fordyce bumps or something that can be cured. So I need some help, I'm too afraid to go to the doctors right now. It would be greatly appreciated.
