This reminds me of the true story of a contract that a husband required his wife to sign and fulfill. I tried a Google search and couldn't find it - but in short, it specified what she could and could not wear in public, how often she had to shower and shave, and how often she had to fulfill the wifely obligations. He did specify exceptions to the sex rules if she was on her period. I think it was on that web site that specializes on mug shots and quirky legal related stories?
Edit - remembered it was on Smoking Gun and found it with a search:
