It sounds like you have nonchlamydial nongonococcal urethritis (NGU), which sometimes is not cured by standard treatments. You'll need to be professionally evaluated in person by a clinic or doctor who understands STDs. I can't solve your insurance problem, except to suggest you probably could be seen at little or no cost at your local health department STD clinic.
The anal irritation is a separate problem, perhaps a yeast infection resulting from antibiotic treatment.
You are correct I do have NGU, but that is a very vague and not the actual cause of the problem as we all know. I know that NGU can be caused by a number of things from soap to herpes! I already went to the STD clinic 12 days ago. I was tested negative for chlamydia and gonorrhea. I returned to clinic for 2nd time and they examined me and decided they would try treatment for trichomoniasis as a last option and if that doesnt help then they have no more answers or help for me. My question is could it be caused by urethral herpes, E Coli, mycoplasma genitalium, trichomonas vaginalis, or prostatitis? Im 23, Male, one female sex partner.
NGU is rarely tested to know the cause other than chlamydia; the usual approach is to just treat with different antibiotics.
For sure it isn't herpes. Prostatitis is possible, but usually doesn't cause urethral discharge. Beyond that, it's usually a matter of guesswork and trying different antibiotics. You'll just have to see a health professional; there's nothing more a nonprofessional community forum can do.
