New York (CNN) -- Could letting your man sleep with another woman help your relationship?Author and former mistress Holly Hill thinks so.
"One of the main things that I have learned is that a woman that negotiates infidelity with her partner is far more powerful than a woman who is sitting home wondering why he's late from the office Christmas party," she says.
"It's better to walk the dog on a leash than let it escape through an unseen hole in the back fence."
Hill's memoir, "Sugarbabe" details her yearlong adventure with a series of so-called "sugar daddies." The book sold 24,000 copies in her native Australia, according to her publisher, and has just been released in the United States. Holly Hill is a pen name.
