So around 4-5 weeks ago I had gay unprotected anal sex with another male. He says he doesn't have herpes but I'm not sure. I've had symptoms including burning urination, and some greenish discharge that I've seen like twice in the mornings. I got tested for chlamydia gonorrhea and trich and hiv and came back negative for all of those. I haven't had any painful sores or blisters that I am aware of. Is getting a herpes test at 5 weeks worthless? And does this sound like it can be herpes?
