Here's another reason

internet porn is so stimulating

and so addictive.

It takes advantage of an old program

located in your primitive brain.

This subconscious program

is what got you started down the path

of using porn.

Consider this experiment.

It's been done many times.

I guess scientists have nothing better to do.

What happens when you drop a male rat into a cage

with a receptive female?

Well,

first you see a frenzy of copulation.

Progressively, the male tires of female #1.

She wants more but he's had enough.

He just can't get excited anymore.

So, what do you do?

Well, replace the original female with a fresh one.

And the male revives

and gallantly struggles to fertilize her.

He keeps on going

then the same things happen.

The male loses interest in female #2.

Starting to see a pattern here?

This process can be repeated again and again

but with novel partners.

Now,

I'm not sure how many times

this can be repeated.

But this can be repeated

until the male nearly dies of exhaustion.

See, this is a genetic program.

This has nothing to do with your genitals.

It's all happening in the brain.

And the purpose of it

is to make more babies

but even more importantly,

is to increase the genetic variety

of the male's off spring.

Here's an interesting graph,

which happens to be about rams.

As we can see,

we have female presentation at the bottom,

we have time to ejaculation in minutes

on the left side

and we have a male.

In one experiment,

the male had the same female

over and over again

and in another experiment

he had different females.

How long did it take him to ejaculate?

Well,

if you look at the same female,

he got longer and longer

until finally I guess

when they stopped the experiment.

It took 18 minutes.

Now, a ram only lives 12 years

so 18 minutes is like 2 hours in our time.

So it's quite a bit of time.

And of course

with different females,

he ejaculated quite quickly

which of course

means he was very very excited.

If you think about heavy porn users,

they often need more novelty

just like these animals, to get excited.

Here's what's going on with the animals.

It's called the Coolidge effect.

It starts out with declining interest

in the present sexual partner

then renewed vigor in a novel sexual partner.

This is present in all mammals,

and it 's also present in females and

of course, we said

it's here for the genetic variety

of the off spring.

This is what started you down the road

to getting hooked on porn.

You see, with porn,

you're like a lab rat.

Your primitive brain urges you

to fertilize the two-dimensional females

or whatever is on your screen.

So, you're happily married and partnered up,

you'd say,

“No, I'm never going to cheat!”

Well, either way,

the Coolidge effect

is still at work in your brain.

The more rational parts of your brain are saying,

“No, I'm not going to cheat!”,

but the primitive parts of your brain are saying,

“Wow, look at that!”

or maybe fantasizing

what would it be like to have sex or

maybe you're using porn.

This is a subtle reminder of

the deep programming of your brain,

the Coolidge effect,

that's there to spread your gene far and wide.

Speaking of looking,

maybe we're not so unique.

Here's an interesting research.

The headline is

“Monkeys Pay to See Female Monkey Bottoms”.

What are they paying with?

Well,

monkeys love sweets like fruit juice.

So, in a study,

the male monkeys would give up their fruit juice

in order to look at female bottoms.

You know, this is a little bit like porn,

or maybe a lot like porn,

monkey porn.

Here's the limbic system,

the primitive brain

where the old program is installed

is often called the limbic system

or mammal brain.

It's the part of the brain we have in common

with all mammals,

including that monkey we just saw.

It's true we have only a single brain,

but certain parts have specific jobs.

This part is ancient,

hundred million years old or older

and its job is all about survival.

Now, I could spend an hour

talking about all of its functions,

but what's important to us

is that it governs emotions,

such as fear, joy,

anger, etc.

And importantly,

it is also the seat of

most of our desires and our drives,

including hunger,

mate selection and our sexual urges.

You see,

sexual desire or libido

is not in your genitals.

It's here,

this is where you experience the Coolidge effect

and where all addictions happen,

including porn addiction.
