One of the big misconceptions is that affairs or trysts are flings about sex. And sometimes they are, but much more often they are about desire. And that is very different. The desire to feel special, to feel seen, to feel appreciated, to be laughed at or with. The desire to be desired. That does not manifest in a sexual act per se. Affairs make you feel alive. Alchemy means it's not about the actual sex, but the sexuality, the energy, the aura. It's the imagination and anticipation of it as much or instead of the actual experience of it.

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?

People cheat on each other in a hundred different ways: indifference, emotional neglect, contempt, lack of respect, years of refusal of intimacy. Cheating doesn't begin to describe the ways that people let each other down.

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.

Secrecy fuels erotic intensity because it makes you feel like you're doing something that is entirely yours. It gives you the sense of autonomy, the sense of freedom, and the sense of sovereignty. And then you add to that the sexual energy. In many affairs, people will tell you they slept with the person three or four times, but the story went on for months. That's an important thing because many people who have affairs often have very good sexual relationships at home. It's not necessarily a compensation story. But affairs offer a different sexuality with a different context.

There is no neediness in desire ... there is no caretaking in desire. Caretaking is mightily loving, [but] it's a powerful anti-aphrodisiac.

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."
