Small red bumps almost look just like pimples but in somewhat of a patch. Goes from the pubic region above my penis to just below my bellow button to the right and left side. I suspected after sex with my girlfriend it was that she just shaved and she was rubbing her genital region up and down almost like a grinding motion. Although the bumps have been around for at least 14 days. They don’t itch, red with a white center and they won’t pop at all. Guess severe friction caused them but im worried
