Can my semen be causing sore urethra after ejaculation? Had test after test. Still no diagnosis.

Answer is NO. Semen doesn't cause soreness in urethra UNLESS you have infection.Sometimes what we ingest MAY irritate the urethra. You also have testis ,back ache..What did the urologist state after cystoscopy ? If you had prostatitis, Cipro (ciprofloxacin) should have helped.I like to know the finding on cystoscopy...........
