i have had sex twice, two different partners and wore protection both times. i have since noticed these small white bumps on my scrotum. they are under the skin, they are flesh colored when relaxed and white when you stretch the skin out. it looks like a pimple but doesnt pop. feels like a little stone almost. im afraid it might be a wart but matches more the description of a cyst. i dont shave down there although i have plucked a few hairs from my scrotum, could that have caused an ingrown hair. i have a doctors apointment in three weeks, but i need to know if this might be an std so i can prepare myself for that. im extremely worried and appreciate any help. WHAT IS THIS
