Many couples have never had a conversation about sexuality and sexual boundaries. The presence or lack of sex, the quality of it, the satisfaction and dissatisfaction, the unmet needs. An affair upsets the status quo by not only bringing the subject of sexuality to the forefront but every other aspect of their relationship as well. An affair yields conversation that should have happened in the beginning, but that people were afraid to have because, well, what would that mean about their relationship?

The power of transgression is the archetypal, foundational story of the Bible. We want to break our own codes - sometimes of morality, sometimes of ethics, sometimes of the power structure, sometimes of the institution of marriage - because there is freedom and power in transgression.

You never know your partner as well as you think.

People grow up learning to be silent about their sexuality, so where are they going to learn to talk about it when they are in a relationship? Shame, guilt, ignorance, reservation, prudishness, all kinds of different cultural systems and social stereotypes shroud sexuality in secrecy and in silence. And there's the romantic notion. "If I say in the beginning, that I am missing something, you are instantly going to think that means you are not enough."

Real sexual conversations are enormously intimate and beautiful because they reveal so much about who we are and what we want. What are the emotional needs we bring to our sexuality and how do we connect to ourselves and connect to a partner? There's such a rich tapestry that can be revealed, but the vast majority of couples have never had those talks.

For me, the constitutive element of an affair is the secrecy. It is the secrecy that leads to the lying, to the deception, to the duplicity. It is the structure of an affair - not the sexual or emotional behavior or what people actually are doing.

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.
