What a great idea! If all women kept their husbands in chastity and made them crawl around we would have a much more peaceful society.

Eventually an element of fear for the husband could be introduced while he is crawling around the house. Establish "no go zones" where if he accidentally crawls into them while looking for the key he will be severely whipped or caned while tied to a trestle.

Or the dominant wife could make it even more amusing by restraining her husbands crawling movements - eg by limiting his crawl length with a  chain attached from his ankles to his ball sack!
