im a 21 year old male. im also umcircumsized. On nov 3 2006 i had protected vaginal sex with a sex worker. Recently i've discovered four pimple like bumps under my penis between the head and the foreskin. when i scratch them they come off and bleed a little. i have had no pain or discomfort or any symptoms.
My question is couuld this be an STD or even HIV??
