Hi cat lady and welcome to the group of wives who are struggling with the same sadness and feeling of loss, due to the effects of hormone treatment.
My husband and I(we see this as a problem for both of us) are further down the treatment path than you, and in all honesty I don't think it has got any easier after nearly 3 years.
We are slightly older than you. I have reached the grand old age of 73, and he is 70 next month, and it would be fair to say our sex life had tailed off a bit before his diagnosis, but was still an important part of our lives. Since he began HT in 2016 he has had no desire at all. I think we have a close relationship still, but like your husband he has no wish to kiss and cuddle, or even to walk hand in hand. I think he has some idea that something is missing, and I know he makes a real effort to show affection to me, but we are both aware of the missing link in our relationship, and I think it does cause some tension. When he was diagnosed and the possible effects of hormone therapy and radiotherapy were explained to us, I felt he would be much more effected by the loss of sexual feeling than I would, but at that time we didn't understand how completely his sexual desire would disappear. We live in hope that some desire will reappear once hormone treatment finishes, we tried to persuade our oncologist that 2 years of treatment would be enough, having read that some people are saying the three year programme may not be all be necessary, but no luck there, and having him here is by far the most important thing.
I'm sorry I can't offer anything more positive, but I can assure from what I have read on here you are not alone. It does help if you can find someone to talk to, but it is not easy to talk to family as even in these much more open times, it is a very sensitive matter to discuss. I think all men going through Prostate Cancer feel a loss of masculinity, and sometimes it feels like treading on eggshells!
The only real suggestion I would make is to talk to each other as much as possible, and concentrate on all the things you can share.
