Sex: How It Works

---

We're going to head to the

bedroom and the lab to unlock

the mysterious world

of sex we all live in.

To discover the truth

behind the female orgasm,

we'll watch as a woman climaxes

in the name of science.

PROF KOMISARUK:
Start

genital stimulation.

MONICA:
Donating an orgasm for

science, how bad could that be?

NARRATOR:
Reveal how

micro-machinery allowed a man

to experience an erection

for the first time.

COLIN:
... that's was a

thirty-thousand dollar erection

that you just saw.

See if a pick up artist can help

a 30 year old virgin overcome

his fear of approaching women.

KURT:
... just wondering where

you got your fancy outfits at,

they're... they're neat!

NARRATOR:
And find out if

alcohol really does make people

more sexually attractive.

POP GIRL:
One drink and

just start making out,

have a good make-out session,

and I'm ready to pull off

my pants for you.

ROB:
Sex is for fun, sex

is for, uh, excitement.

TIFFANY:
With me being a virgin

there are some things I just

won't know until we have sex.

COLIN:
Being surrounded by other

guys in hockey locker rooms

the conversation of sex

comes up all the time.

NARRATOR:
To reveal just how sex

works we're going to take you

on a journey from virginity,

via arousal, to birth.

And where better to

start, than a bar?

A place where humans have been

hooking up for generations.

But this isn't just any bar;

we've tricked it up with the

latest gizmos, to show how even

when you think you're in control

it's your sex drive

that's doing the talking.

Meet our volunteers - 8 men and

8 women who've never met before

and who, for now,

are being kept apart.

DR LINDA:
Be as honest as you

can we'll see where we all are

at the end ok?

NARRATOR:
The expert in charge

is Dr Linda Papadopoulos

psychologist and sex expert.

DR LINDA:
Sex drive is integral

to the human condition,

without it, humanity as

we know it would die out.

We need to have sex drive.

NARRATOR:
Dr Linda is going

to subject the volunteers to a

series of tests to reveal if

choosing a potential sex partner

is a conscious choice or one

made by our sex hormones.

And the first step is spotting

a face we like the look of.

DR LINDA:
This is just about

trying to see how aware we are

of what we like.

MALE PARTICIPANT:... if she

gives me a little challenge,

a little push, maybe

some attitude, some sass!

Y'know, I like that.

DR LINDA:
If we are talking

about evolution it's all about

passing on your genes and what

you want in a future mate.

NARRATOR:
The first part of the

test is to see if pictures of

the women will arouse the men in

ways they're not even aware of.

DR LINDA:
Men tend to be more

visual that women when it comes

to what they find enticing

which partly to do with how men

are socialised.

If you look at the vast majority

of pornography out there...

vast, vast majority, it's

directed towards men.

This is Jon...

Hi... Hi how are you doing...

So what we want to do it see how

you respond to different images

of women.

So we're going to do

a couple of things,

this is a galvanic skin response

monitor so it's gonna basically

just look at how

you are reacting.

We're also gonna look at pupil

dilation and finally we're gonna

get to look at how you look

at faces through our imaging

techniques. Ok?

MALE PARTICIPANT: Ok, cool.

NARRATOR:
What the men don't

know is that they're going

to meet the women in

the pictures later.

JON:
Ok, you're good to go.

DR LINDA:
We're done?

Ok, so just come through here.

So make yourself

comfortable on the stool.

This is the eye tracking

computer so basically what

it'll do is it'll interpret how

you look at different things.

Beyond that, enjoy looking

at pretty girls, ok!

MALE PARTICIPANT: Ok.

DR LINDA:
We are using an eye

tracking technique to look at

where people look, but at

where they look the longest.

What you find is that we'll have

these big red dots on everyone's

face so if they look at the

eyes the longest, the red dots,

they'll be over the eyes, if

they look at the lips they'll be

over the lips.

NARRATOR:
Other devices will

also monitor changes in heart

rate, perspiration levels

and pupil dilation,

to reveal physical and emotional

responses that the men have

no control over and may not

even know are taking place.

When a man sees an attractive

face the so-called reptilian

part of his brain can react

by triggering the release of

neurotransmitters such as

Epinephrine - accelerating

the pulse, sweat production

and increasing pupil diameter.

The man's body is now primed

to pursue the object of desire.

By analysing how the

men's' bodies react,

Dr Linda can see which of

the women excites the men

at a biological level.

DR LINDA:
How was that?

MALE PARTICIPANT: That was good.

DR LINDA:
A couple of girls

piqued you interest there..

I wonder if you are

aware of what we saw?

Which are the 2 girls...?

MALE PARTICIPANT: Possibly,

yeah, there was one or two,

yeah. Correct, yes!

NARRATOR:
The data indicates

it's the women with thicker lips

and larger eyes that get

the men's hearts pumping.

This could be because these

faces point to a greater level

of fertility, as females with

such features tend to have more

of the sex hormone oestrogen.

Hi! Hello...

The results from one

subject stand out.
