Did you know there are six different types of cheaters? Funny – all this time we thought there was only one: the low-down dirty scoundrel type.

But Dr. Doug Weiss, president of the American Association for Sex Addiction Therapy and founder of the counseling site SexAddict.com, explains to BettyConfidential that cheaters come in six varieties. And while not all cheaters are sex addicts, Dr. Weiss implies that serial cheaters, in particular, may have sex addiction issues.

Before we check out that sex-fueled six-pack, we asked Dr. Weiss for his thoughts on the Tiger Woods Cheater’s Open, which is still very much in play. (Tiger’s tally of alleged infidelities has now reached 14. AshleyMadison.com, the infamous dating site dedicated to cheaters, even offered Tiger a $5 million endorsement deal, according to TMZ.com.)

So is Tiger’s wandering golf club the result of a man with so much power and influence he thought he could have whatever – and whomever – he wanted?

“It doesn’t have anything to do with success or fame; garbage men and plumbers…are cheating too,” says Dr. Weiss. “Sexual addiction runs the gamut of every color, race and wage.”

Dr. Weiss, himself a recovering sex addict who’s appeared on Oprah, says that no one is a lost cause, however. “They can all get better,” he insists, “they just have to want to.”

So what about those six types of cheaters – and where does he think Tiger falls? Dr. Weiss explains in an interview and through excerpts of his new book, Addicted to Adultery: The Other Reason Spouses Cheat:

1. The Hunter Cheater

They are looking for the weak, needy or another sex addict for a quick hit. They tend to have pickup lines or a clear modus operandi to capture their prey. The hunter is rarely looking for an equal, because an equal could hurt them. This could be a doctor or lawyer whose prey is the secretary, waitress or woman at a bar. They tend to be the smart, successful, smooth-talking guy who exudes a certain sexual or narcissistic energy. It’s all about them and their needs. The stench of entitlement is also present in the hunter’s heart.

Whoa – can we have Tiger for $2,000, Alex? Dr. Weiss says Tiger clearly fits the hunter pattern, seeking a very specific prototype of woman who is young, beautiful, thin, in-shape and willing.

“These were not multimillionaire women, not big sports stars, not actresses,” Dr. Weiss says of the women Tiger allegedly targeted. “None of these women had power; they were not threats.”

2. The Hero/Nice Guy Cheater

This is the person who “wants to help.” They want to rescue the maiden in distress, so to speak. This person wants to be a friend to their victim, talk about the victim’s life, marriage, kids or job. The hero/nice guy’s adulterous heart is quick to praise, quick to appreciate and quick to pick up on cues as to whether you are starting to trust them. They get excited when the victim trusts them, because they are close to the kill. Even after sex, they want to be seen by the victim and themselves as a nice person.

“Heroes want a woman to tell them, ‘You’re wonderful,’” explains Dr. Weiss.
