The secret to desire in a long-term relationship

In this amazing video Ester Perel tries to answer the questions: How can we sustain desire in long term relationships and why is it so difficult? What is the erotic intelligence?

“So, why does good sex so often fade, even for couples who continue to love each other as much as ever? And why does good intimacy not guarantee good sex, contrary to popular belief? Can we want what we already have? That’s the million-dollar question, right? And why is the forbidden so erotic? What is it about transgression that makes desire so potent? And why does sex make babies, and babies spell erotic disaster in couples? It’s kind of the fatal erotic blow, isn’t it? And when you love, how does it feel? And when you desire, how is it different?”
