You know what happens to sex in marriage? Instead of inviting desire, you monitor it. Especially men: You let her sleep late, you take the kids to the park, and all that time you're thinking, "Tonight I'll get some." That doesn't work.

Modern love is the enterprise that everyone wants to be a part of, yet there's a fifty percent divorce rate in round one and a sixty-five percent divorce rate in round two.

It's our imagination that's responsible for love, not the other person.

When we seek the gaze of another, it isn't always our partner we're turning away from, but the person we have ourselves become.

There is not one person who can fulfill all your needs. You may choose a partner who is your intellectual equal, and he may not be your most compatible sexual partner. And then there's the duality between security and adventure. A relationship that gives you plenty of novelty, and adventure, may not provide the stability you long for. Time, continuity and familiarity with somebody gives you other things in life but won't necessarily give you the kind of intense lustful experiences that you may have when you first meet someone and are curious about penetrating the mystery of them.

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.

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?
