Best wishes for a good outcome from your surgery. I was diagnosed with prostate cancer at around the age of 50 (I'm 71 now) & ended up undergoing a radical prostatectomy. During my recovery period I developed a double hernia that had to be repaired. (I was told that's not all that unusual.) I also ruptured a disc in my low back that, since then, has impinged on my sciatic nerve. So I've had sciatica as well, although as time has passed this has become less of an issue.

As a result of my prostate surgery I've been impotent ever since & have struggled with some minor incontinence issues. So, anyway, I have some familiarity with what you're dealing with. In my case I was fortunate to be married to a woman for whom sex was never a major factor. So my loss of sexual ability was not a major concern. Hopefully you will find that your wife's commitment will remain strong as well. Best wishes...
