Hey Robert... I had RP (laparoscopic) surgery last August (about 13 months ago)... Was lucky not to require additional treatments as cancer was isolated. Surgery was kind of brutal. Multiple skewers (tools/camera) through core abdominal muscles and cutting and suction (also had complication of previous hernia surgery mesh that was somewhat "in the way"). I was 62 and 3/4 at the time. I had never experienced any form of ED and was very strong in that regard. Got no real assistance in that regard post-surgery. Surgeon basically said - "oh yeah, you won't have erections for a year..." Had to initiate active treatment myself to try to get back on track. Talked with a buddy who went through similar who was super-helpful. My family physician is a friend who was extremely helpful when asked (he had similar ED-creating surgery himself years earlier). So, he prescribed Viagra and/or Cialis - told me to try/experiment - see what worked best for me. Started at about the 9-month mark (should've been sooner I guess - but my primary struggle post-surgery was incontinence - which I have made remarkable strides with, also had a freshly torn A-C ligament in left shoulder - ugh!). Even before drugs, I was getting some nocturnal blood flow - but very partial. Also could create some blood flow without prescription with significant stim. But a far cry from pre-surgery. The scripts have helped somewhat - probably getting me to about 70-75% with significant stim. Like you, I am hopeful for non-drug full return, but it is not there yet (I am not interested in injections or pumps at this point). My family physician told me he had recovery all the way to 3 years out! I also had significant pain along perineum post-surgery - I have even been doing red light therapy almost daily along that track - bought my own light panel (supposed to help cellular recovery at the mitochondrial level). I am determined to recover fully - but it is work. There are some good resources out there - google: "Victoria" "A Touchy Subject" - she has some good discussions, videos, options... I am treating this like any other injury from a "re-hab" perspective - many have taken time and determined effort. Best to you!
