Dr. Wendy Walsh

How many guys have you slept with in your life?

Zero.

Okay.

I've slept with more than 100.

I think I know them really well sexually.

There's a wide range of sexual behavior.

No, you could have said three.

I was a hot model in my teens and 20s.

I had lots of time to experiment.

So I, yeah, I really think that there are a lot of guys out there that also feel pressured to have sex a lot because some men like you who enjoy a lot of frequency of sex, which is absolutely okay, spread a message that you're not man or you're not masculine if you don't want to have a lot of sex.

You know, okay, so let me explain how anthropologists figured out how much monogamy or promiscuity is in a culture.

They look at a species scrotum size.

Stay with me.

Look at the five primates.

At one end of the scale, you got chimpanzees.

Chimpanzees,

huge gonads in relative to body size, very promiscuous, very violent, all the testosterone.

In fact, what they will do if they meet a nursing mother is kill that baby.

They practice a lot of infanticide to bring on estrus in her and make her more fertile so he can rape her.

Then the other end, you've got these big hulking orangutans.
