Let's start with the beginning, i had sex with a girl about 3 weeks ago after couple of days a small red or brown dots appears on the head of the penis no itchy and underskin and didn't cause any pain, although there was no other symptoms, i went to my doctor he told me this couldn't be a sign of std amd gave a medicine, like oil to rub the head, they disappeared after 3 days, but my friend who lives with me had noticed today similar spot on his penis, could this be a kind of rush. Or what is it. I can't stop thinking about this thing please help, and is there something you recommend
