How long has it been there?
It could just be a pimple, or various other things. Hard to tell.
it jut showed up today i had sex yesterday with my girl and it wasnt there
it doesnt really burn or itch
Could possibly be a pimple of some sort. A build up of something.
so nothing to worry about
Did you use a condom? Put a little dab of undiluted LIQUID antiseptic on this 3 or 4 times a day and see if that will help it to heal …
