Hi Doc,
I'm 23 years old, circumcised. I've always had urine collect in the tip of my penis after I pee -- my flow is fine, but I have to cajole urine out with my hand after I finish.
Anyways, about a year ago I started developing this problem where I would develop a prickly, burning rash around the tip of my penis after sex. I also had slight burning in my scrotum and slight nerve sensation in my butt. I abstained for three months, got a full STD test (all negative) and then, my fears assuaged, I had an unfortunate night where I had unprotected sex and did not come (I've abstained since). The next day was bad. I couldn't urinate at all, and my penis was totally red and inflamed. A few days later my scrotum became fire-truck red and leathery and started burning intensely, and I felt this ferocious pulsing sensation in my butt. The scrotal burning eventually subsided over the course of several months, and I had another full round of STD checks at three months after that (again negative). However, the rash is still there and the tip of my penis remains sore and overly sensitive. The rash is generally quite faint, except when I shower, sweat, masturbate, after a night of drinking or right after I pee -- then it becomes bright red. The only time I've seen it improve is when I went swimming in the ocean -- the cold salt water seemed to shrink it. Also, I still get a pulsing sensation in my butt as well.
I've had swabs taken for candida, yeast and bacteria, all of which came back negative. I also went to a urologist, who felt my prostate and diagnosed me with prostatits. He put me on 2 weeks of Cipro, which hasn't really seemed to help, and flomax.
What is causing this rash on the tip of my penis by the urethral opening (it looks like it may even extend a little bit down into the urethra)? And also, if I have prostatitis, why would having sex and not finishing cause such a horrific reaction? Will this happen if I try to have sex again?
Thanks for your counsel.
