"Beat it like it owes you money." Rofl Epic!
On a serious note...I am curious as to why this rule should exist in the first place.

With all due repsect, it seems utterly ridiculous. As long as your alone time (so to speak) doesn't cut into your sex life (and provided you don't leave her without lotion or ruin the good towels or some such)...why on earth would she care?
Go ahead and do what you've gotta do, I say. Wouldn't say a more than once weekly routine (or daily really) is detrimental, but...lol just remember not to beat the poor guy into submission and you should be fine.
Hoping your wife gets better soon.
Hugs,
Harley
