Sticky clear mucus. Have? what s wrong?

Hello! 3 weeks ago, i discovered a high volume urethral secretion, white coloured and owith odour, which caused my pants  some yellowish spots.Next day, had a swab culture, turned negative. Did my hiv and syflis tests, also negative The physician prescribed 3 days 2 times a day ciprofloxacyn, and 7 days after doxycicline. In these period, the urethral discharge decreased, and it became just clear and only when milking urethra. In the 5th day of doxyiclin, i had been tested again with culture swab and NAAT for gonorheea and chlamydia, all test negative. The symtoms persists with clear discharge, testicle pain. I went to an urologyst which prescribed me an antiinflamatories and once a day azyhromicin for 5 days. I m in my 3 day on azythromicin, the symptoms are worse: pain urinating, burning also and clear sticky uretral discharge Also today i had an urine test that showed presence of mucus, i am also waiting for the results for uryne culture. What bts do I have? Or ..what s wrong?
