About a week ago, I started experiencing some occassional stinging / burning in my urethra, itching on anus, and
pain/tenderness in the epididymis. It's possible that I was exposed to both gon. and chl. during an anonymous sexual encounter that I had. This was exclusively oral sex involving mouth, penis, and anus. No discharge, rashes, or sores that I can discern.
I have been diagnosed in the past with chronic prostatitis, for which antibiotics sometimes help.
