“For marriage as we know it to survive in the future, we will all have to catch up. Things are shifting dramatically in our society. We are learning a new form of relationship — not based on sex, or swinging or adventure — but based on integrity, a new concept for many of us. Being out in the open about our real feelings many be a new and creative style of relating. This type of relating is not founded in following our lust or our impulses but is the basis of forming a new style of relationship that is honest — honest with ourselves about what we really want and desire and honest with our partners about what we need. There is an inherent maturity in standing up for what we believe is our truth — even if it is the need to love more than one person at a time.”
