Bruce,
I am a little late in this thread but you need torelax until you have the biopsy results back. There is nothing you can do now about this so why send any time needlessly worrying. You either will have PC or you will not. If you do have PC there are so many courses of treatment that can provide you with a long life and positive outlook. I was diagnosed last year on my 61st birthday and had robotic surgery early June and was 100% continent by July 4th last year and have been since. I like you was much more concerned about being dry than the ED issues as I knew my best sexual years were behind my wife and I. I will not lie a year after surgery I have serious ED and use injections for erections and sex. However, I feel so much better now than before my diagnosis and I realized I suffered for years with a prostate that made peeing very difficult and I NOW pee like a teenager again. After you get your biopsy results back I hope you will post again here as there are so many here who will help you through the decision process on choosing the treatments all based on our individual experiences and PC journeys.
