Ok I know for sure I dont have an std, because i'm a little embaressed to say this, i'm a virgin. I have these very tiny bumps under my pennis. Their not red their the normal skin color. They dont hurt what so ever or does it bother any of my pennis functions. Their incredibly small but I can see them and theres a large one at the bottum of the shaft. Remember I am a virgin and parents dont have stds.
