What if the reason is health related and the other party does want to have sex? Should the neglected spouse bring up the issue with the ill spouse? It seems to be a very touchy subject.

Remember the vows...in sickness and health....if you truly love the person, and she/he is too sick to engage in intimacy, cheating is not acceptable. Also, bear in mind that even though she/he is sick don't mean she/he don't want to have sex they still have desires but can't act on them.

Why is there an assumption of cheating when the questions seemed to be geared toward how to handle the situation with the ill spouse. I don't think there's a third party here. Anyone have experience with this and is it healthy to shut down sexually?
