Most affairs do die a natural death. Today, you look at your partner's phone to find out the weather, and you find out about a lover. It has never been as easy to cheat as it is today, and it has never been harder to keep a secret.

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.

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."

You never know your partner as well as you think.

Acceptance doesn't mean predictability. Sex isn't always for 11 at night - - it's also 'meet at a hotel room at noon'. What you feel during dating can exist at home, if you don't suffocate it.

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.

Most of us will get turned on at night by the very same things that we will demonstrate against during the day - the erotic mind is not very politically correct.
