Marriage isn't meant to make you happy - it's there because it gives you a life in which you can find happiness.

The mom doesn't become sexy; the woman does. You have to retrieve the woman from the mother. And she may need to separate to do that: a bath, a walk. She must cordon off an erotic space.

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.

As a teenager growing up in Europe, I embraced the romantic ideal. For me, I had to give up the ideal that one person would be there for everything. Once you give up that ideal, then you begin to accept the person that you are with - the person who won't be able to give you everything and who won't be able to know exactly what you want and feel without you even needing to say it.

Affairs can be powerful detonators. They can invigorate a marriage that's flat, jolt people out of years of complacency. Fear of loss rekindles desire, makes people have conversations they haven't had in years, takes them out of their contrived illusion of safety.

What is the relationship between love and desire? How do they relate, and how do they conflict? ... Therein lies the mystery of eroticism.

The whole notion of one person being enough for everything gets instantly challenged when you start to talk with somebody about wanting more or of wanting something else. They take it personally, feel like a failure or feel that they lack something, so you don't talk about it because you don't want to hurt, offend, or scare the other person. You also don't want to be rejected or have them leave you, whatever the reason.
