Had non nerve sparing surgery for prostate cancer a year ago. Then raduotherapy and hormone tablets. Awaiting results in february to see if clear. 

Question is , i been using the injections for trying to get erection. One type if medicine i never respnded to at all even tho we went up to 40m per needle. Then used another which only has one strength and it done something but not near good enough for penetrative intercourse. im awaiting to go back to hosp re this also But has anyone been unsuccessful too? Im worried tbat their isnt anything more to try. I tht the injections wd work successfully for everyone.  please help
