@anet Hi and this may be a bit uncomfortable since I'm a man and your issue is not only a woman's issue. I cant help with the medication issue and would leave that to his doctors but I can relate to a sexless marriage. I love my wife very much and similar to your issues(except yours is from you Husband) she feels uncomfortable during intercourse basically it hurts. Now I do feel left out as it seems when our intimacies stopped so did any touching even hand holding or kissing has disappeared. She like you husband seems uninterested in finding a solution. I personally think when I started having Health issues ( I have had a Heart Transplant) is when the other things declined. I see you mentioned Church and I am very dedicated to the Lord and ministry in general so I suspect for me that's a factor also. She does not attend church and so except for walking, shopping and dining out we don't have much else to share. So i hope at least this helps to know your not alone and Ill say your story helps me also.
I just myself try not to dwell on what we don't have and concentrate on what we do. I try to think that I did promise to Love in sickness and health and remember my vows. What if one of us had a serious accident and no longer had any body functions would that be a deal breaker? So I'm not much help, but for me knowing that the Lord knows my Prayers and as He told Paul about his thorn in the flesh "My Grace is sufficient" and remember someday we all will be in Heaven and enjoying a perfect Life that actually doesn't include physical sex but that the Joy we have is greater than what the this world has to offer by many times over .
I hope that at least gives some comfort and keep praying as the saying goes "But God" he can maybe change his outlook going forward in you Husbands drive.
Blessings
Dana
