That's just what I was going to say.
However, a lot of the disabled people I know didn't start out that way, so their marriages already had the base on which to survive the no sex thing.

Mental intimacy is far more important to me, being able to think in the same direction.
People's jobs and such take them away sometimes, and it's a shame if the lack of sex is the only thing that kills a relationship.

I would rather my husband didn't get his dick cut off in an industrial accident, but it happens, and I'd love him just the same....
