I have been having sex with the same partner for the last three years....well just 5 weeks ago I had UNPROTECTED sex with a new partner. 2 weeks after intercourse I experienced a bloody discharge from my penis during a bowel movement, which is still occurring. The blood only comes out when i really bear down on my stomach. Also, I am ejaculating alot faster than normal when my gf and I have sex. I have no symptoms other than these. I do not notice blood any other time. The symptoms dont appear to be getting any worse, but they dont seem to be going away either.

I went to E.R a day after symptoms started, and got a gonhorrea/chlamydia and prostate examination. I also gave urine samples on 3 different occasions, no bacteria or blood could be found in my system. I was also sent to the hospitals urologists whom diagnosed me with prostatitis, for which i was prescribed doxycycleine....
Does this sound like a correct diagnosis?
