If your S/O developed a health condition that eliminated the possibility of any form of sexual intimacy, what would you do?

Say your S/O was in a car accident and became disabled. Or, say your S/O developed a chronic illness. Regardless of the condition, if sexual intimacy was no longer possible because of health reasons, what options would you consider? Would you remain monogamous to your S/O even if it meant long-term celibacy? If so, generally speaking, how would you take care of your sexual needs?

Regardless of your hypothetical decision, why would you choose it?
