Sex and needing intimate contact with your husband when he can't sucks. No doubt about that. I suggest you have a frank discussion with him about your needs.
My husband had a back injury a couple of years ago that made it too painful for him to have sex. I had to figure out other ways to take care of our need for physical intimacy (and I am not just talking about sex) and how to make sure I was still satisfied without going nuts (I'm 34).
Issues with his heath snowballed for a while, but I was determined to make sure both us still had our needs and desires met for however long I had to be solely responsible for it. Things like vibrators and other marital aids helped get me through patches when the husband wasn't able to have sex, but you MUST make sure you maintain some kind of physical intimacy with him if at all possible. If he wants to participate in what you're doing to satisfy yourself and it's medically alright for him to do so, let him.
A big reason sex is so important is there is as much need for physical intimacy as there is for emotional.
Talk to him. Talk to him with his doctor is you need to do so. There are many, many ways to bring what you need back into the marriage provided he is healthy enough to do it and both of you are willing to do things in unconventional ways.
