Say tomorrow something happens to you. YOu become unable physically to have sex in ANY form.
You're completely paralyzed from the neck down.
Would you expect your spouse to remain celibate for the rest of your life? Considering you can feasibly live for a VERY long time..as in decades..in that condition..would you expect that of him?
If the situation were reversed..would you expect that of yourself? Would HE expect celibacy of you?
