Is It Right To Punish your Partner By Denying Him\her Intimacy.

Recently a friend of my woman  Friend told me she refuse to sleep with his man because he refuse buy her the Aso-ebi dress she demand for. I told her it was wrong for her to do so, even bible condemn it give ceaser what belong to ceaser. i dont encourage anyone to avoid his men because of money. I advice her to be submissive to his partner.
