I had oral sex a few days ago. I noticed some uncomfortableness a few days later which turned into swelling and then these pimple like dots. I have no symptoms of any std but these red dots are scaring me. they are not painful and it looks like my body is doing the healing process of whatever has happened. could it be an allergic reaction to the person i recieved it from of some kind?
It could possibly be a skin irritation. Have you observed any discharge from the urethra? How do the bumps appear when erect? Have the bumps changed in size since first noticing?
