Inflamed Penis and ichy

I had sex with a condom and while in the process I felt a short burning feeling near the head of my penis...after sex, I checked the condom and it was not broken. Regardless, The next day I felt a slight burning feeling near the head of my penis. I also had 2 small dots on the rim of the hood of my penis. I went to my GP doctor that day and had blood and urine tests. He said the 2 dots were normal...even though I never had them before.
MY GP gave me Tetracycline. 3 days later, all the tests came back negativie while my condition slowly felt worse. I started feeling inflamation in my urertha and burning in my rectum. I returned to the doctor and he referred me to a urologist.

The urologist did blood and urine test to check for all stds..again all the tests came back negative. He also checked my prostate and did a culture test. He said I might have slight Prostatitis and put me Levaquin. After 3 weeks, my condition worsened. I had pain and inflammation in the scrotum and a very itchy rectum, plus mild burning after urination or ejaculation.

After another week with little to no releif, I returned and asked for prescription Metronidazole. I explained that my symptoms resembled Trichomoniasis...all except I have no discharge. I tryed Metronidazole(even though my urologist said "good luck with that") But it did help a little with the itching.

It was been 6 weeks now and my symptoms still come and go...I feel frustrated and depressed. The next step is to get a scope...But, now I am afraid I might be suffering from Nonbacterial prostatitis...which there seems to be very little western medicine knows how to treat.

Any thoughts would be more then appreciated.
