Today I noticed that I have formed small red bumps on my penis head and the area exposed when the foreskin is retracted. I am uncircumsized, and am worried about this. They don't itch or hurt, but there are many of them. ONly one is on the head though. They are 1mm wide, give or take. I also have a bump on the shaft of my penis, but i thought it was just acne and squeezed it, and as usual, acne stuff came out and i thought nothing of it. I am 17 years old and had oral sex with a male recently. I trust him enough to tell me if he had any STDs, but I'm very paranoid about this at the moment.
Is there any chance of an STD here?
