About two weeks ago i was receiving head and gave her oral, we tried sex, it was unprotected we got the head of my penis in but then it hurt her too much and had to pull it out. well about 3-4 days ago i've started to find these Pimpel like things on my head (only a few) and a few on my shaft. Now their sorta more like really red spots then pimpels but seem a lil like pimpels. What cud it be? allergic reaction or something of some kind maybe?
