Recently I was with this guy and was performing oral sex on him and I noticed that he had a dry spot on his penis. I didn't think much of it and thought.. okay, well maybe he has dry skin on his penis? After he got lubed with my spit the dry spot went away.Although the next day, I am concerned now in that a bump formed on the side of my mouth which discharged some blood but it has since stopped and I haven't been feeling anything weird in my mouth after that encounter.Anyone have any ideas? Or maybe I just had a coincidence in getting a sore the next day, like a minor herpes simplex 1 virus?Also, I did eat some rough food too that day, so maybe the food caused the bump and cut my mouth?
