My boy friend and I were doing 'The Do' but when He pulled out his penis was bleeding. I have looked up STD's and bacterial disease and he has no pain, no other signs of anything but for that. No swelling of the eyes, anus, no diffrent smell no diffrent color or smell discharge, nothing. He tryed to tell me that when him and his last girlfriend were having sex, he hit something (like her walls maybe) and said when he pulled out he was bleeding. He likes to tell me that mayb it's scared and it opens every time we have sex, can you please help me find out if he has a STD of infection?
