Negotiated Infidelity

Most of Hill's "daddies" were wealthy married men who surprisingly often opted for conversation, she says. While entertaining with red wine and exotic food platters she'd prepare in her Sydney apartment, Hill learned that most of these men sought her attention because they simply weren't getting enough sex from their wives.

"Men need to get their rocks off," says Hill. "If a woman crosses her legs for any length of time and doesn't arrange some sort of alternative for her man, he is going to cheat on her."

By alternatives, Hill is referring to her idea of "negotiated infidelity." That shouldn't be confused with an open relationship, which to Hill "has no rules." Nor does it imply that it's necessary that a wife allow her husband to hop into bed with whomever he chooses -- unless of course she's OK with that. Hill says negotiated infidelity could mean hubby makes a trip to the local strip club for the occasional lap dance or updates his porn collection.

And in no way does it have to be a one-way street.

"Ideally the woman will want to stray as well," says Hill. "Some won't want to because they're at home taking care of toddlers. But the woman definitely needs to negotiate infidelity as well, especially because that will generate her man's competitive nature. The more lovers the woman has, the more attraction the man will have for his partner."
