I am 20 years old and recently had to go in for surgery for a urethral stricture a week ago today (1/5/10). I have found the recovery to be more annoying than painful. I recently became nervous about my reproductive system due to the surgery, as im sure most males my age would be, and decided that i felt healed enough to masturbate. When i ejaculated i felt fine but my semen was a little bloody which concerned me. But afterwards i felt intense burning pain underneath my scrotum. I went to sleep and the pain eventually went away but this morning i woke up, urinated as usual with no pain or discoloration. Directly after i urinated a good amount of blood/clotted blood came out with any pain for about 10 minutes on and off. The bleeding has stopped for now but I am just concerned how long should i wait until i can masturbate/have sex after this operation? I have searched the internet with no luck on obtaining any kind of info about this. Any help is appreciated, thanks.
