I think love is often a bit selfish, even before we had consumerism. That's not new. A consumer society gives you the illusion of having massive amounts of choice and saddles you with the freedom of being able to dabble in that choice. And at the same time, you are left with the tyranny of self-doubt and uncertainty about whether you made the right choice.

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.

One of the big misconceptions is that affairs or trysts are flings about sex. And sometimes they are, but much more often they are about desire. And that is very different. The desire to feel special, to feel seen, to feel appreciated, to be laughed at or with. The desire to be desired. That does not manifest in a sexual act per se. Affairs make you feel alive. Alchemy means it's not about the actual sex, but the sexuality, the energy, the aura. It's the imagination and anticipation of it as much or instead of the actual experience of it.

You never know your partner as well as you think.

A peer relationship is one where the partners experience an affectionate, companionate coupledom. They are friends. They are the product of the egalitarian model; they are good life partners, but are often less sexual.

There is no neediness in desire ... there is no caretaking in desire. Caretaking is mightily loving, [but] it's a powerful anti-aphrodisiac.

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.
