This occur after a week of unprotected oral and condom vagina sex. I was stressing after the sex, got tested a few times, all negative. Saw uro, was on doxycycline 7 days,azithrom(1 dose), and melixicam 7 days and thought I was fully heal. Two days after symptom came back Fri night, then went away until today(tues) I was washing penis in acv diluted but that's not helping now. I notice the more I stress the intense it gets. It's hard NOT to think about your penis...I'm going to see uro.again Tom. Can someone give me any insight to what's causing this? There's no sore,discharge or other pain..urine has a strong odor tho...please help me get rid of this
