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.

In desire, there must be some small amount of tension. And that tension comes with the unknown, the unpredictable. You can close yourself off at home and say, "Whew, at last I'm in a place where I don't have to worry," or you can keep yourself open to the mystery and elusiveness of your partner.

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.

The meaning of secrecy is very different when the model of love is one of transparency. So to understand the politics of secrecy and revelation, you need to understand the larger culture in which the couple lives and also the culture of the couple itself. What does intimacy mean to them? Where does the couple draw the line between togetherness and separateness? That's what informs you. You always ask, "What would happen if I tell? What would happen if I don't tell?" Sometimes, the partner doesn't want to know.

In committed sex, in marriage, people don't feel the need to seduce or to build anticipation - - that's an effort they think they no longer need to do now that they have conquered their partner. If they're in the mood, their partner should be too.

In dating, if you say no, your lover goes on to the next person. In marriage, if you say no, the person stays.

You never know your partner as well as you think.
