herpes

I've had zits on my cock before... especially if I've been sweating a lot, or if I've just had a lot of hard, grinding sex. The latter especially if I have recently shaved part of the shaft, then with a lot of grinding... the hair follicles tend to get irritated and often form bumps.
 
A (straight) friend of mine had a red lump come up on the shaft of his penis. I know he's not sexually active (good Catholic boy) and he showed it to me on webcam... It'd been like it for a couple of weeks. I said "Is it sore?" He said it was a little tender. I asked what happens if you squeeze it? He said "Dunno" and gave it a little squeeze there and then on webcam and it popped. It was just a spot. Bless him.
 
well ı have a same problem ı went to doctor he gave me a cream antibiotic he said its just an infection after sex because ı didnt use condom..but its been a week but thy didnt heal yet there is like 5-6 red zits on my cock..ım really worried too damn
