You will never be able to say women have nothing to offer, because, at least, they will always have their own bodies. When your body is useless and it can't do anything of worth, you can only offer your body itself.
Your wife is pretty much just a sex object for your bully. Nothing but a toy for him. So why would he share his sex object with you? Isn't it only reasonable you never get to see her naked again? He owns her tits, not you.
