Let me back up.

We did a survey and we asked people, what time do you have sex?

72% of people have sex between 10.30 and 11.30 at night.

Here's what's interesting, is when you look at your hormone profile, it's the worst at that particular time.

Here's the hormones that you need to successfully be intimate with a partner.

Estrogen, testosterone, progesterone, adrenaline, and cortisol all need to be elevated, and melatonin, the sleep hormone, needs to be lowered.

You correctly identified, we ain't got no adrenaline and cortisol at night.

We've got it all in

the morning time so that is hint number one as to when to have sex hint number two if you happen to be having sex with somebody who was born biologically male what do most men wake up with in the morning an erection if that is not mother nature telling you when to use that thing i don't know what is so what ends up happening is most people however still have sex in the evening time

because they don't understand the biology of these chronotypes.

So it actually gets pretty fascinating.

Believe it or not, the most read chapter in my book is the chapter on sex.

I actually have a chart in there because here's the interesting thing.

What happens is you're an early bird, but your partner is a night owl.

What do you do?

So I actually have a matrix where you put your chronotype on one side and their chronotype on the other.

And I give an early evening and an early morning time for intimacy.

And I have everybody try it out and let me know what works best for them.

Here's what's fascinating is we did a survey of people afterwards and we discovered that for men, they actually function better sexually.

So longer erections, reach orgasm better and last longer.
