Dale -- what does your wife think about
this? Can you still give her affection without any actual intercourse? And is she happy with that?
If not, can you induce any kind of erections at all? You might find injections help or maybe just Viagra. And there are of course ways you can (try to!) satisfy her without actual penile penetration.
I appreciate that intercourse will seem a chore for you, but perhaps it is a chore you undertake for now because you love your wife. Think of it as payback time for all the chores she has probably undertaken for you. I don't know this for sure, but you might actually enjoy it somewhat once you get started.
Not having had Lupron treatment, my questions/suggestions may be way off the mark or too personal. If so, please ignore them.
