PPP is generally located on and around the ridge of the glans, not the foreskin. If you have tiny whiteish spots on your foreskin, they are probably Fordyce spots. Agian they are harmless spots caused by overactive sebaceous glands. The spots you are noticing on your shaft are just hair follicles and normal sebaceous glands. All guys have this on their shaft and scrotum area. The variocele is no big deal unless its large and bothersome. The frenulum is something that can be stretched out if you work on it. Ask your doctor about steroid creme which can help in the stretching process. Overall, you're just over reacting to these things. You'll be fine.
it's called frenulum breve, and it's not uncommon.
to fix it, you don't even need the steroid cream. regular stretching will loosen the tight frenulum. just gently pull on it, taking care not to rip it, several times a day, for several minutes. I say take care not to rip, because if you do, you need to stop all sexual activity, including masturbation, for a couple of weeks until it completely heals.
