"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."
