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.

For some people, the experience of sexuality is that they are entirely inside their body, but others feel they have totally transcended the physical boundaries of their body. Transcendence is the ability to no longer feel you are contained within the physical world. For many people, the definition of spiritual is a sense of complete abdication of the self. For some people, it's union with another that transcends the borders between where one stops and where the other person starts and creates a sense of infiniteness and timelessness.

For most couples who come to me - especially in the aftermath of the revelation of an affair, when they are in a state of crisis and fear the loss of a predictable future - they start to have conversations for the first time about love, sex, monogamy, and marriage. Most couples don't negotiate or don't even converse about any of these things until the crisis of the affair has actually forced them to. Why does it take infidelity to get us talking about the stuff that should be there from the start?

Love is a vessel that contains both security and adventure, and commitment offers one of the great luxuries of life: time. Marriage is not the end of romance, it is the beginning.

The one word I hear when people have affairs is that they feel alive. They don't talk about the fact they're having sex. They feel like they are engaged with their life. They describe an experience that beats back the deadness inside, which isn't the fault of the marriage or the partner. It's often the deadness that they have allowed to creep in for years on their own. But by definition, it's a transgressive act. And transgression is a breaking of the rules. And it gives you a sense of ownership and freedom. And ownership and freedom gives you a feeling of aliveness. It's a chain.

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.

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.
