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.

You never know your partner as well as you think.

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."

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.

On some level we trade passion for security, that's trading one illusion for another. It's a matter of degree. We can't live in constant fear, but we can't live without any. The fear of loss is essential to love.

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.

If a woman isn't feeling sexual with herself, she won't respond to advances from any partner, male or female. When this woman goes dancing, she's finding a connection with her own erotic self. It might be about being on a dance floor, feeling free, not having to feel at all responsible for anybody else's well-being. For other people, it might be about going on a hike for four days by herself and reconnecting with nature and strength and endurance and beauty.
