 It promotes honesty and integrity. You are not attempting to live a double life. You are not faking an attraction to your partner while secretly fantasizing about having an affair with Sherry or Jay. It enhances trust and communicates how much you value your partner. Boy, if she could share that with me, I can really trust her. She must really value me more than Jay. It helps you and your partner communicate about the possible reasons for an extramarital attraction.
