Personally, I would take it as a challenge to find out how far you can go using my hands. I would either end up with an answer or carpal tunnel syndrome. Of course great care would have to be taken to keep your privates from getting sore and therefore not making a valid test. Does your husband like challenges like this?
BTW, a truly marathon session like that should be good for dieting as there is little time to eat anything with calories.
