In the past couple years the female memberships are growing at a much faster clip than the male memberships are—is that correct?

Absolutely... In the early days it was married women signing up, looking for married men. That was 99 percent of the communication. Today, 17 percent of that communication is to single men. So there's not even a word in the English language. We both know what a mistress is. What's a male mistress? What do we call him? He's a newfound creature.

In the last 10 years—the rise of Kim Kardashian and Paris Hilton, Hillary Clinton might be the next president who herself as survived infidelity—we feel very differently as a society about marriage in general, we get married later and later in life, about monogamy, about having kids, and certainly about unfaithfulness. And women are leading that charge for the most part.

So you're selling infidelity as a manifestation of female empowerment?

Yeah. You know, I've been characterized as many things. Some evil. But almost as like a post-modern feminist. I'm leveling the playing field between two. If you're married to a women today who out earns you, you're at the biggest risk of any man of your wife being unfaithful. It's not about her being blonde. It's not about her having fake boobs. It's not about any of these other factors. If she out-earns her male counterpart, if she's flipped the traditional dynamic. She's more likely to have an affair than anyone else. And that's fascinating.

So by those lights, sex is about power, not love?

I think an affair accomplishes a whole bunch of different things. At its core, it's sex. But it's also about excitement. People always want excitement... having the same vanilla is boring.

What women want, especially women of power, you know, they might be feared or respected or whatever, but they want that feeling of wanting to pursue them. Of being wanted. So that's what they're also looking for in those relationships. So they love it. If they're 38 and their husband maybe makes love to them once every three months or says one nice thing a year about their hair or whatever, they want some 29-year-old saying you're the most gorgeous thing ever, you're like sexual napalm. They want to hear those things.

Your concept of sex is quite different from the way it's conventionally taught.

What's clear to me though is it's not a self-fulfilling prophecy. I'm married, I don't know if you're in a relationship, but I've never met a single married person in my life in my travels, who says, yeah, yeah, since I got married, my sex life just gets better and better and better, and now 20 years into it, we are doing it like bunnies every day. It doesn't work that way... So co-habitation kills intimacy. It just does. That's a fact of biology, genetics, life. Whatever you want to blame it on. I think that's irrelevant in time. I'm one of those people who's just looking at the big data. I'm like the Google of Infidelity. I get to see 1.2 million communication strings sent on my servers everyday. And this is what they're saying.

What's the most shocking revelation of all that data?

Let's start with one like the seven-year itch. It's not. Men cheat three to four years into their marriage and it coincides with a pregnancy or a first-child being born. That is so offensive to so many women. That's like the most outlandish thing but again, like the way we started this conversation was, hey, affairs are very pragmatic. It's kind of like, 19 weekends in a row, a Mother's Day where you're totally neglected again, well, why do men do that? Because, prior to that, their sex lives were going a 100 miles an hour. It was whenever they wanted, whatever room they wanted. Now all of a sudden, their partner doesn't feel up to it. He doesn't physically like her appearance. Maybe she's had the baby, is recovering. And men don't adjust well to being in that desert. And they're really thirsty. They're not prepared for that. Nobody took them aside and said, hey, this is the most exciting time of your life, and it's the worst of your sex life, get ready for it.
