In December of last year, I had protected sex with a partner (not my wife) once. A few days after that, the tip of my penis began to hurt. It was a dull pain and just on the surface. There was never any discharge from my penis. I had a number of exams and urine tests but they all come back normal. A few weeks later, I began to have bladder problems. At first it was just frequence unrination and later on have problem emptying my bladder. My urulogist first thought it was prostate enlargement and prescribed Flowmax and then switched to Tarasozin. Later he decided it was prostate infection and give me 30 days of Cipro. I am about half way into the 30 days now but it doesn't seems to help. Lately when i examine the tip of my penis, it looks like there are very small bumps on the surface. Another symptom i have is problem urinating while sitting down. Sometime I have to return to the bathroom soon after I poop so I could pee. I am 42 years old and in basically good health before this.
