I've had so many comments since my post "ED no more" that I felt I should offer more.
I'm a neophyte on this site. As a matter of fact I avoid this site. I have always adopted an "ignorance is bliss" attitude towards life and my PC. My wife, on the other hand, is a nervous but adventurous individual. We had learned from a friend who is also a fellow PC fighter and he introduced me to Radioligand therapy. He had two rounds in Germany and spoke highly of it. We took a chance and found ourselves in a Thai oncologist's office convincing him that I would be a test case for Lute 177 treatments without going through the the usual protocol of exhausting all the other standard treatments before moving on to lutetium. He agreed and wrote me up. He was as interested as we were to see if I would have a more favorable response by being fit and not having a history of debilitating PC treatments before the Lute treatments. Four rounds of Lute and 20 rounds of focused IMRT later I received a year and a halves worth of Lupron and sent home to Canada. I asked what to expect when I finished the HT and he said: "We'll see". I spent the 18 months slowly losing my ambition, my aerobic capacity and watching helplessly as my testes shrunk and my morning 'woodies' became none existent. I thought I was doomed to be relegated (lifelong) to being "the vibrator guy" in our intimate relationship. But low and behold - I had my last hormone shot 9 months ago, my PSA still holding as "undetectable " at 0.01 and my running returning to a comfortable 5K with much more aerobic capacity. Two weeks ago I felt a stirring and as the days past I was able to achieve penetration after two years of frustration, sexual insecurity and even jealousy. Three days ago I responded to Cialis and had a life changing moment where my super attractive wife and I flew over the moon and cast off all of my insecurities. ED no more (my wife teases me that I am more obsessed than when we were dating).
