Your husband’s behavior is actually very common for people who have a sexual addiction. There is a term for it: Sexual Anorexia—he starves you sexually because he no longer needs you—he has videos which don’t demand anything from him. He has actors on a stage who seem to give him all he needs, and they do not expect anything.
