For some people, the experience of sexuality is that they are entirely inside their body, but others feel they have totally transcended the physical boundaries of their body. Transcendence is the ability to no longer feel you are contained within the physical world. For many people, the definition of spiritual is a sense of complete abdication of the self. For some people, it's union with another that transcends the borders between where one stops and where the other person starts and creates a sense of infiniteness and timelessness.

Our consumer economy peddles the notions "romantic consumerism" of finding "the one," of being the one. It's the narcissistic enhancement of, "I'm the one you stopped your nomadic life for." It's one thing when you have sex for the first time when you marry, but it's another thing altogether when you stop having sex with others when you marry. So the marital commitment becomes, "I must be really special. With me, you no longer think you can find better next door." Romantic consumerism is thinking you can't find better, younger or newer.

There is not one person who can fulfill all your needs. You may choose a partner who is your intellectual equal, and he may not be your most compatible sexual partner. And then there's the duality between security and adventure. A relationship that gives you plenty of novelty, and adventure, may not provide the stability you long for. Time, continuity and familiarity with somebody gives you other things in life but won't necessarily give you the kind of intense lustful experiences that you may have when you first meet someone and are curious about penetrating the mystery of them.

To look at infidelity from the point of view of sex is a complete narrowing of the phenomenon. There's a reason that the commandment is repeated twice in the Bible - once for doing it and once for thinking about it. We have always created structures and broken structures. It is essential to the human spirit.

Women - - and men - - need to understand that a woman's transition is often much longer. The caretaker must leave the place of orientation to the needs of others to the place where she focuses on herself.

I do consider even going to prostitutes, or seeing a hooker or an escort, as having an emotional component, even if it's not an emotion necessarily in the relationship. Even if you are paying in order to absolve yourself of any emotional involvement. That's the paradox.

At this point, we are living one of the greatest experiments in humankind - to create something that has, throughout history, been considered a contradiction in terms - a passionate marriage. Passion has always existed, but it took place somewhere else. Everything that we wanted from a traditional marriage - companionship, family, children, economic support, a best friend, a passionate lover, a trusted confidante, an intellectual equal - we are asking from one person what an entire village once provided. And couples are crumbling under the weight of so much expectation.
