The approach you must take is a loving and responsible one. Saying things about how you would like to have sex with someone other than your spouse will surely hurt their feelings and it will not get you anywhere. Probe questions such as “have you ever fantasize about having sex with other people?” followed by a loving gesture that it is not a trick question will do the job almost every time. You will be able to determine whether they are interested or not just by watching how they answer this question carefully.

Remember, you should never push your spouse into swinging. Your partner needs to understand the loving and trusting nature of the lifestyle and commit to it voluntarily. Otherwise, the whole experience will be a definite relationship breaker. Be sensitive as you explain to them about swinging and how both of you can benefit from the lifestyle. Answer their questions objectively and let them be comfortable enough to tell you about their fantasies as well. If the responses are positive, you can talk more about the lifestyle and find resources that can help you and your partner understand swinging even more.
