Did Madonna give Guy rules for sex?! It sounds absurd, but rumor has it Madge made her rules clear by posting them on the wall of their Manhattan pad.

London tabloid The Sun is reporting the rules are no rumor! What are these lovemaking laws? The kooky couple agreed to "devote time to sexual expressiveness" and "not use sex as a stick to beat one another."

Rumor debugger Perez Hilton breaks it down, saying, "I think this is just another piece of false information coming from the rumor mill."

Sun sources say M "pinned the contract up" after the Ritchies saw marriage counselors in 2006.
