At this point, we are living one of the greatest experiments in humankind - to create something that has, throughout history, been considered a contradiction in terms - a passionate marriage. Passion has always existed, but it took place somewhere else. Everything that we wanted from a traditional marriage - companionship, family, children, economic support, a best friend, a passionate lover, a trusted confidante, an intellectual equal - we are asking from one person what an entire village once provided. And couples are crumbling under the weight of so much expectation.

Sex is about where you can take me, not what you can do to me.

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.

Love is at once an affirmation and a transcendence of who we are.

The secret to desire in a long-term relationship

The very ingredients that nurture love - mutuality, reciprocity, protection, worry, responsibility for the other - are sometimes the very ingredients that stifle desire.

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.
