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.

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.

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?

You never know your partner as well as you think.

One of the most amazing abilities of sexuality is to momentarily transcend the borders of Self into something that is no longer defined by physical property and that is utterly unique. It's really what many call a religious experience.

Real sexual conversations are enormously intimate and beautiful because they reveal so much about who we are and what we want. What are the emotional needs we bring to our sexuality and how do we connect to ourselves and connect to a partner? There's such a rich tapestry that can be revealed, but the vast majority of couples have never had those talks.

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.
