The picture isn't clear and I'm not sure how much I can help, especially when 2 different hands-on docs (including a urologist) haven't come up with clear answers. Your symptoms suggest urethritis, ie inflammation/infection of the urethra. The most common cause after oral sex is nongonococcal urethritis (NGU), due to any of several possible bacteria, including the otherwise normal bacteria from a partner's mouth. However, NGU usually takes 5-10 days to show up. The 2 day incubation period suggests gonorrhea. Most gonorrhea responds to cipro, although in recent years resistant strains have been increasingly common, especially in gay men. Most gonorrhea and NGU cases would respond to doxycycline--so the apparent absence of response to that antibiotic doesn't make much sense. By "gland" your urologist undoubtedly means the prostate, i.e. possible prostatitis (which is not sexually acquired and would have nothing to do with your oral exposure). But infectious prostatitis usually would also respond to one or both of the antibiotics you have received. Some cases like yours probably are due to non-infectious inflammation of the urethra or prostate, in which case it will not respond to any antibiotic.
So I cannot help with your diagnosis, because nothing fits very well with your story. You'll have to say it is very unlikely you have anything that you can transmit to your wife, and probably nothing that will ever harm you either.
I hope this helps. Good luck-- HHH, MD
Is that an opinion, or a definite statement?
