of literally thousands of people for the past 28 years,

and one thing I have found, or one thing I know,

is that most of us have experienced that wild and out-of-control feeling

at the beginning of a new relationship.

You know what it's like

where you can't eat, you can't sleep, you can't get anything done

because you're constantly thinking about this person.

Your heart's racing,

you feel that adrenaline rush when you see the other person,

and basically, you just want to be with that person.

It's almost like an obsession.

I bet if I asked you to close your eyes,

you could definitely think back

and remember that powerful and amazing feeling

that affects us physiologically.

I know I can,

and I've been married for 22 years.

But when we're in that heightened arousal state

at the beginning of a new romance,

many of us step back and ask the question:

"What am I feeling?

Am I in lust or am I in love? Is it lust or is it love?"

What if I told you that you'll never have to wonder again,

because there are four specific signs that differentiate lust from love,

and the two states, lust and love, are completely different from one another.

That would be wonderful, right?

So let's start with lust.

When you're drawn to someone,

based solely on physical and sexual arousal or attraction,

that's lust.

You're filled with sexual desire that doesn't stop,

and all of those sex hormones are being produced in your body

at an alarming rate; you have sex on the brain.

Also, when we're in that heightened state of arousal

at a new relationship, or in a new relationship,

we glorify or idealize our partner.

We don't see them for who they really are.

And in fact,

we see them for who we want them to be or need them to be.

You've heard the phrase "love is blind"?

Well, at the beginning of a new romance, lust makes you blind.

You're impressed

by everything and anything your partner does or says.

In fact, it doesn't even matter

that she has all of her stuffed animals on the bed, plus a few pillows,

or that he has absolutely no idea what a hanger is used for.

You don't see it. It doesn't bother you.

But as time goes on in a relationship,

those same behaviors, those exact same behaviors,

become annoying and irritating to you,

and it's at that point in time that you begin to see

this other person for who they really are; flaws, faults, and everything.

And by the way, yes, we all have flaws or faults.

None of us is perfect.

But at this point in time, lust declines.

And I'm really sorry to disappoint you,

but my research shows that lust declines in all romantic relationships.

It's an inevitable part of all romantic relationships.

I know. Sorry about that. Don't shoot the messenger.

(Laughter)

But can lust be reignited in a long-term loving relationship?

Absolutely!

My work with couples confirms that,

and we're going to talk about how to do that in a few minutes.

But for the moment, it's just important to understand

that lust declines in all romantic relationships,

and if you stay with that relationship, lust can turn into love.

Love it also a profound emotion, and has a physiological foundation as well.

When we're in love, we produce the hormone oxytocin,

which triggers relaxation

and promotes emotional bonding and closeness.

But that's actually the opposite to those wild sex hormones

that ignited all that lust in our body.

Besides the hormonal differences between lust and love,

there are also four cues that you can use to distinguish lust from love.

The first sign is what I call connection.

When you're in love, you want your partner to connect

with all the important people in your life.

You want them to spend time with,

to like, hang out with your friends and family.

You want to show off them to your friends and family,

and you want your friends and family to be impressed by this other person.

Also, you don't keep them to yourself,

but you bring them out and introduce them to your interests again

and the people who are important to you.

The second sign

is when you use "we" language rather than "I" language.

It turns out that when two people are in love,

their lives are intertwined,

and they begin to think of themselves not as separate individuals anymore,

but instead, as a couple.

And the more intertwined these two people's lives are,

the more overlap in their lives, their friends, their interests,

and in their circles in this diagram.

And the more overlap between their lives, the more mutuality.

Mutuality is when we refer to ourselves as a couple,

as an "us" or "we", rather than as an "I", or this other person.

So, for example, if I asked you what you were doing last weekend,

if you were in love, you would tell me, "We went out to dinner",

"We went to the movies", or "We went up north for the weekend",

rather than,"I took Sandy to the movies, and then I went out to dinner",

or "I went up north".

So, if you want to distinguish between lust or love,

look at your language,

and the degree to which you use "we" versus "I" statements.

The third sign is self-disclosure,

what you tell this other person about you.

Love motivates us

to reveal extensive information about ourselves to this other person.

When we're in love, we want to tell this person

about our dreams, our aspirations, our goals, the past, the future.

Sometimes we tell them confidential information,

and sometimes we tell them all of our secrets

that we've never told anyone before.

When we think about self-disclosure in a relationship,

you want to think about an onion.

The outer layers of an onion represent

the superficial aspects to us as an individual,

and as you peel away the layers of the onion,

you get at the core of who you are.

You get deeper,

and there's more information about you as an individual,

personal and intimate information.

So, when you're in lust, you only peel away a few of those layers.

You tell this other person maybe about your interest,

your hobbies, movie, or music preferences, but that's it.

You don't go to the deep core of you.

When you're in love, you go straight to the core.

You share information that has more breadth, more topics,

but each topic also is deeper, more personal in nature.

You go straight to the core.

So, if you want to distinguish between lust and love,

look at what you're talking about

and how many topics with this other person.

The last and fourth sign is that you influence one another.

When two people are in love,

what one person does or wants to do, influences the other person

in meaningful and strong ways.

For example, if you were thinking

about moving to a different state because of a new job,

or you were considering any big change in your life,

you would want to go to your partner before you make a decision.

Likewise, if you had something happened to you -

a medical scare, you actually lost your job,

or the death of a family member -

you would want to go to this person to get social support, assistance.

You would want help from this person.

Or, if you had something good happened to you -

you won the lottery, or you got an award at work -

you again would go to this person

because you would want them to share the good news.

And they actually would celebrate with you.

So, lust and love are completely different from one another,

and couples have a very difficult time

maintaining that urgent longing we call lust over the long-term.

Can you recreate that lust?

Absolutely!

My research shows

that if you add three behaviors to your loving long-term relationship,

you can reignite or rekindle that lustful desire.

And those three behaviors turn out to be the same behaviors

that ignited the lust when you first met that person.

So, if you mirror the beginnings of your relationship,

you can add lust, rekindle that passion in your relationship.

The first strategy to rekindle or recreate the lust

is to do new and novel activities with your partner,

because newness creates excitement.

Think about it.

At the beginning of your relationship,

everything was a new experience for the two of you.

Everything was new and novel.

Every date you went on, every restaurant you ate at

was a new experience for the two of you,

and that created the excitement, and created all of that arousal.

But then, as time went on, the newness wears off.

So if you want to recreate that lust,

you need to find new and exciting things to do with your partner.

That can be as simple as going to a new restaurant

in a different part of the city that you've never been to.

You can try skating, skiing, or snowboarding

for the first time with your partner.

Boy, I have winter on the brain, don't I?

Or, you can, like my husband and I did, sign up for a cooking class.

Neither of us had done it separately, and we did it together,

which fueled the lust.

Anything new will recreate that beginning feeling.

The second strategy that you want to do is to use the element of surprise,

and add a little bit of mystery to your relationship,

because mystery and surprise enhances lust.

The idea is you want that "oh, wow!" factor, right?

You want that to be recreated in your loving long-term relationship.

Again, think back.

At the beginning,

everything was different and interesting that you were learning about your partner.

Yes, she told you that she had a pet snake when she was growing up,

and you went, "What? Wow! Now that's interesting!",

or that he was closest to his grandmother growing up,

and you asked a lot of questions, because that was fascinating to you.

Any new or different, interesting, mysterious, surprising information

refuels that passion and lust.

But then, as time goes on in a relationship,

you begin to really know your partner, almost too well.

You know what they like to do on Sundays, you know that she snores when she sleeps,

and he chews with his mouth open, and he doesn't like the color pink.

You really get to know your partner.

And while that's wonderful,

because that intimate knowledge builds love, it extinguishes lust.

So you again need to add the element of surprise and mystery.

And yes, all of what you're thinking about there

regarding lingerie and roleplaying is adding mystery to your relationship.

(Laughter)

But, you can also do other things.

You can go to your partner's place of work

and whisk them away for lunch, or after work for dinner,

or you can send him a flirty text message in the middle of the afternoon.

One of the wives in my long-term study on marriage and divorce

said that she took her husband on a treasure hunt,

and he went all around the city without her,

but she left these little notes in each spot,

and he found the experience surprising and full of adventure,

and she said it added a little spice to their relationship afterwards.

The third and final way to rekindle that lust

is to do what I call arousal producing activities.

This is my favorite suggestion, but it's not what you think -

I see you all smiling and smirking out there -

(Laughter)

it's actually clean.
