“If you’re cheating on your spouse then why are you with them, “ said David Alba, who lives in the Lower Valley.

The website, Ashley Madison.com, bears the slogan "Life is short. Have an affair."

“I think it’s wrong,” said Maribel Ocana, also of the Lower Valley.

While some believe it is wrong, KFOX went undercover and found El Pasoans logging on. We posed as a married woman who’s screen name was Naughty Nita. We posed as a married guy named Secret Boy Toy. On the Web site you can select if you’re single or attached. You can also put a check next to your interests, such as if you want someone to whisper in your ear or tickle you with a feather.

Naughty Nita was able to sit down and meet two men who admitted that they were married but looking for more.

“I mean It’s not bad,” said the guy, referring to his marriage. KFOX kept his screen name anonymous. “Something on the side. I don’t know, something different on the side.”

We didn’t have as much luck getting a married woman to sit down and meet with Secret Boy Toy.

One woman e-mailed him saying: “‘Well just to let you know, I’m also married. I’m not looking for anything serious. Just a playmate here and there.”

Night Eyes Protective Services private investigator Fernando Rodriguez Sr. said he is not surprised we couldn’t get a woman to meet with Secret Boy Toy. He said women are better at cheating than men.

“Women are planners,” Rodriguez said. They are very astute, very smart, very intelligent. The guy, he’s haphazard.”

Rodriguez said over the last year he’s received roughly 1500 cases and 72 percent of them are men suspecting their wives of cheating. He said most of his cases come from the east side and the lower valley. And he said cheating spikes around the end of the year, because of office parties.

Ashley Madison.com’s CEO, Noel Biderman, believes cheating is natural.

“The human condition is one where we can’t overcome our DNA and men and women aren’t meant to be monogamous,” Biderman told KFOX. “It’s a social construct that we’ve created.”

He said his business does not promote cheating.

“That’s a decision you come to based on your life circumstances,” he said.

Biderman said there are 4, 974 people in the El Paso area that are members of Ashley Madison.com. In Texas, he said there are 135,000 members and 19,285 members in New Mexico. Nationwide, Ashley Madison.com has 2.7 million members.
