This past wed. i had unprotected sex (something im not proud of) with a girl that i have known for a good while. i have masturbated a few times since then. this past sat. nite i recieved a hand job from a diff. girl. when i awoke sunday i saw a little cluster of small red bumps and a few around the shaft. i noticed they appear to be in the areas where a hand would grip around my penis. they do not itch or burn and are causing no irritation. IS it a rash or something i should worry about. Please help i am very anxious and stressed.
