Yes it must be pretty difficult for wives, I did 'pleasure' my wife occasionally but she actually wasn't too bothered as going thru menopause affected her for a while anyway.
We're all different as they say 're effects/recovery etc., some say it is not uncommon for effects to last as long as we were on HT for. In my case it wasn't too far from that, I was on Zoladex for 3yrs and it was certainly 2years before libido returned.
That is just my experience though.
Best of luck
