I had brief unprotected oral dating back to July 7th and one other encounter two days after, both interactions were less than a minute of oral. On Saturday July 16th, I started to notice slight burning at the start of urination which progressed into itching/irritation in urethra. Urination only has slight burn at the beginning and goes away after start, also no pain during ejaculation. This prompted me to test for gono and chlamydia Monday morning, test came back yesterday afternoon and were both negative. I certainly have had some anxiety fueled milking that has probably made irritation worse looking for discharge. Had slight discharge this morning after gently squeezing the tip of my penis. Do you think there is any chance this could be NGU? Based on what I have read trich or mycoplasma genitalium are thought to rarely transmit through oral. Am I letting my mind get the better of me?
