I had a full radical prostrate removal 11 years ago.. for the past 6 years most of the time when I orgasm I have extreme sharp pain at the end of my penis ..sometimes it will occur a couple of hours later at which point I find I can t pee and have extreme pain for sometimes 18 hours.. I can t go in the cold when this happens.. I notice it is very frequent when I masturbate usually a couple of hours later.. any ideas thanks greg
Pain is related to prostate.  You have not given the reason of radical protect Tom. Whether twas benign or malignant condition. Urination or ejaculation there will be spasm in prostate and blade sphincter.  This will radiate pain to tip of penis. Consult neurosurgeon who has operated for further follow up and precaution.
