You never know your partner as well as you think.

For some people, a one-night stand doesn't make any difference in a seven-year love affair. I don't believe the degree of betrayal is always commensurate with the egregiousness of the behavior. They are two separate things.

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?

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.

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.

As a teenager growing up in Europe, I embraced the romantic ideal. For me, I had to give up the ideal that one person would be there for everything. Once you give up that ideal, then you begin to accept the person that you are with - the person who won't be able to give you everything and who won't be able to know exactly what you want and feel without you even needing to say it.

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.
