I had one instance of unprotected sex in mid/early december and about 4-6 days later I had about 8 lesions on my penis as well as the penis head being tender with an off-white/yellowish discharge. There was also a painful/burning sensation when peeing. I saw a Dr. a week later who said the lesions looked like herpes and the discharge was probably bacterial so he sent me to get tested, both urine and blood. The results came back negative across the board (herpes included). Is there a time frame for detection? It was about 2 weeks from unprotected sex to lab testing.
