Is it ok to coach your husband if he consents?

I feel like my husband could really benefit from actual coaching. I am wondering if he is open to it (which he could very well be). I would ask him first.
But if he wants, could I do his models and help him see things differently if he wants?

I feel a bit weird. I want to make sure I am not pushing him on it, but if he says he does want to then is there anything against the rules?
