What is the ruling on a wife urinating on her husband's clothes before intercourse, when each of them requests that from the other, along with the evidence?

These behaviors indicate a deviation in conduct and a perversion of innate disposition. Neither of you is permitted to do this to the other, as it is religiously forbidden to touch impurity without necessity. Therefore, you are not permitted to obey your husband in this matter, for obedience is only in what is good and permissible. We also advise moderation in love and avoiding excess.
