In the off chance you in fact had a urethral infection, clarithromycin
in the dose you took would have cured it. That includes gonorrhea
, chlamydia, or the (largely unknown) bacteria that cause nongonococcal urethritis (NGU).
There certainly has been no medical reason to avoid sex with your wife all this time. Had I been in your situation, knowing what I know, I would have continued unprotected sex with my wife. At this point you certainly have no worries about it.
I hope this helps.
