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?

Or, the next question would be,

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?

These are some of the questions

that are at the center of my exploration

on the nature of erotic desire

and its concomitant dilemmas in modern love.

So I travel the globe,

and what I'm noticing is that

everywhere where romanticism has entered,

there seems to be a crisis of desire.

A crisis of desire, as in owning the wanting --

desire as an expression of our individuality,

of our free choice, of our preferences, of our identity --

desire that has become a central concept

as part of modern love and individualistic societies.

You know, this is the first time in the history of humankind

where we are trying to experience sexuality in the long term,

not because we want 14 children,

for which we need to have even more because many of them won't make it,

and not because it is exclusively a woman's marital duty.

This is the first time that we want sex over time

about pleasure and connection that is rooted in desire.

So what sustains desire, and why is it so difficult?

And at the heart of sustaining desire in a committed relationship,

I think is the reconciliation of two fundamental human needs.

On the one hand, our need for security, for predictability,

for safety, for dependability, for reliability, for permanence --

all these anchoring, grounding experiences of our lives

that we call home.

But we also have an equally strong need -- men and women --

for adventure, for novelty, for mystery, for risk, for danger,

for the unknown, for the unexpected, surprise --

you get the gist -- for journey, for travel.

So reconciling our need for security

and our need for adventure into one relationship,

or what we today like to call a passionate marriage,

used to be a contradiction in terms.

Marriage was an economic institution

in which you were given a partnership for life

in terms of children and social status

and succession and companionship.

But now we want our partner to still give us all these things,

but in addition I want you to be my best friend

and my trusted confidant and my passionate lover to boot,

and we live twice as long.

(Laughter)

So we come to one person, and we basically are asking them

to give us what once an entire village used to provide:

Give me belonging, give me identity, give me continuity,

but give me transcendence and mystery and awe all in one.

Give me comfort, give me edge.

Give me novelty, give me familiarity.

Give me predictability, give me surprise.

And we think it's a given, and toys and lingerie are going to save us with that.

(Applause)

So now we get to the existential reality of the story, right?

Because I think, in some way -- and I'll come back to that --

but the crisis of desire is often a crisis of the imagination.

So why does good sex so often fade?

What is the relationship between love and desire?

How do they relate, and how do they conflict?

Because therein lies the mystery of eroticism.

So if there is a verb, for me, that comes with love, it's "to have."

And if there is a verb that comes with desire, it is "to want."

In love, we want to have, we want to know the beloved.

We want to minimize the distance. We want to contract that gap.

We want to neutralize the tensions. We want closeness.

But in desire, we tend to not really want to go back to the places we've already gone.

Forgone conclusion does not keep our interest.

In desire, we want an Other, somebody on the other side that we can go visit,

that we can go spend some time with,

that we can go see what goes on in their red light district.

In desire, we want a bridge to cross.

Or in other words, I sometimes say, fire needs air.

Desire needs space.

And when it's said like that, it's often quite abstract.

But then I took a question with me.

And I've gone to more than 20 countries in the last few years

with "Mating in Captivity," and I asked people,

when do you find yourself most drawn to your partner?

Not attracted sexually, per se, but most drawn.

And across culture, across religion, and across gender --

except for one -- there are a few answers that just keep coming back.

So the first group is: I am most drawn to my partner

when she is away, when we are apart, when we reunite.

Basically, when I get back in touch

with my ability to imagine myself with my partner,

when my imagination comes back in the picture,

and when I can root it in absence and in longing,

which is a major component of desire.

But then the second group is even more interesting:

I am most drawn to my partner

when I see him in the studio, when she is onstage,

when he is in his element, when she's doing something she's passionate about,

when I see him at a party and other people are really drawn to him,

when I see her hold court.

Basically, when I look at my partner radiant and confident,

probably the biggest turn-on across the board.

Radiant, as in self-sustaining.

I look at this person -- by the way, in desire

people rarely talk about it, when we are blended into one,

five centimeters from each other. I don't know in inches how much that is.

But it's also not when the other person is that far apart

that you no longer see them.

It's when I'm looking at my partner from a comfortable distance,

where this person that is already so familiar, so known,

is momentarily once again somewhat mysterious, somewhat elusive.

And in this space between me and the other lies the erotic élan,

lies that movement toward the other.

Because sometimes, as Proust says,

mystery is not about traveling to new places,

but it's about looking with new eyes.

And so, when I see my partner on his own or her own,

doing something in which they are enveloped,

I look at this person and I momentarily get a shift in perception,

and I stay open to the mysteries that are living right next to me.

And then, more importantly, in this description about the other

or myself -- it's the same -- what is most interesting

is that there is no neediness in desire.

Nobody needs anybody.

There is no caretaking in desire.

Caretaking is mightily loving. It's a powerful anti-aphrodisiac.

I have yet to see somebody who is so turned on

by somebody who needs them.

Wanting them is one thing. Needing them is a shutdown,

and women have known that forever,

because anything that will bring up parenthood

will usually decrease the erotic charge.

For good reasons, right?

And then the third group of answers usually would be

when I'm surprised, when we laugh together,

as somebody said to me in the office today,

when he's in his tux, so I said, you know,

it's either the tux or the cowboy boots.

But basically it's when there is novelty.

But novelty isn't about new positions. It isn't a repertoire of techniques.

Novelty is, what parts of you do you bring out?

What parts of you are just being seen?

Because in some way one could say

sex isn't something you do, eh?

Sex is a place you go. It's a space you enter

inside yourself and with another, or others.

So where do you go in sex?

What parts of you do you connect to?

What do you seek to express there?

Is it a place for transcendence and spiritual union?

Is it a place for naughtiness and is it a place to be safely aggressive?

Is it a place where you can finally surrender

and not have to take responsibility for everything?

Is it a place where you can express your infantile wishes?

What comes out there? It's a language.

It isn't just a behavior.

And it's the poetic of that language that I'm interested in,

which is why I began to explore this concept of erotic intelligence.

You know, animals have sex.

It's the pivot, it's biology, it's the natural instinct.

We are the only ones who have an erotic life,

which means that it's sexuality transformed by the human imagination.

We are the only ones who can make love for hours,

have a blissful time, multiple orgasms,
