Ok a week ago i noticed red bumps on my penis 2 on my penis and 1 under my foreskin. hoping they will go away they havent they have multiplied and have gotten bigger and new ones have came in, they are around 2mm big and some very small. They do not itch or cause any pain or any burning sensation when i urinate. im scared i have caught an std from having unprotected sex around 2 weeks ago. it has not spread to my scrotum at all just under my foreskin and penis please help!.
