Swingers Next Door: Married Couples in This Ohio Neighborhood Spice It Up With Neighbors Married couples in this Ohio neighborhood spice it up with neighbors.

 -- Tony and Diana have been married for five years and have three kids together.

Their days spent doing craft projects with their kids or getting them ready for school makes them seem like an everyday, normal family from Cincinnati, Ohio. But Tony and Diana, who asked that their last name not be used, have a secret.

They are swingers, who actively swap sexual partners and host swingers parties for their suburban neighbors.

Tony and Diana are such proponents of the lifestyle, they even agreed to appear on a new reality show on A&E called “Neighbors With Benefits,” which premieres on Sunday, March 22 at 10 p.m. ET.

Tony, who owns his own construction company, said he loves watching his wife have sex with another man.

“It’s an extension of myself, watching her pleased and stuff from different angles. Man, I feel awkward saying all this,” he said. “I think there definitely needs to be a healthy amount of jealousy in every relationship, especially a swinging relationship.”

The husband and wife said they are very picky when it comes to choosing partners to have sex with, and they have rules.

“If we didn’t meet you in the lifestyle and we were friends before, we will not ever cross that boundary,” Tony said. “Our friendship is way, way, way more important than any sexual fantasy could ever be.”

“We have group texting,” Diana said. “We have individual texting. I’m comfortable with Tony individual texting another girl. I guess I could look at his phone any point in time if I wanted to.”

Tony and Diana’s love story begins like many young couples. Diane said Tony was a “typical 21-year-old” when they met and had a wandering eye.

“I didn’t really want to settle down, I just wanted to have fun,” Tony said. “I just wanted to party.”

Diana said she had never even heard of “swinging” until Tony introduced her to it, but once she tried it, she said she was on board. But swinging does have it downsides.

“Jealousy is always a big issue for some people, especially first getting involved in the lifestyle,” Diana said. “It’s a hurdle that you have to get used to and kind of adapt to.”

“She’s still my wife, I love her very much, I’m very protective over her,” Tony added. “We made that decision to move forward. She didn’t do it on her own, and I didn’t do it for her. We did it together. And that’s what makes the ups and downs I think easier for us, is we are trying to do it as a unit and not trying to do it as my fantasy.”

“We’ve been open and out to our communities, for our families, for five years,” Diana said. “So it’s not much different.”

To pick up potential couples to “play” with, Tony and Diana will go to bars or clubs, or they will spend a night at home with other couples into the swinging lifestyle, while their children stay at a friend’s house or with a babysitter for the night.

“We are responsible most of the time, but that doesn’t mean that, our eyes are closed to opportunities if they arise,” Diana said.

But the swinging lifestyle is drawing criticism from near and far. Mark, whose last name is also not being used, lives next door to Tony and Diana and said “I was shocked to learn what was happening next door.”

“It’s not positive for anyone,” he said. “I’m not here to judge”

A spokesman for Citizens for Community Values, an activist group against the reality show, declined “Nightline’s” requests for an on-camera interview, saying in a statement they would be staying focused on their social media campaign to get “Neighbors With Benefits” off the air.

But Diana and Tony say they have no plans to give up the swinging lifestyle anytime soon.

“We’ve been doing it since day one,” Diana said. “So we don’t have any other way to compare it to.”

And after marriage and three kids, they say swinging has brought them closer together.

“Our relationship is good because of the communication and a lot of relationships are lacking that, and we really got the tools to do that through swinging,” Tony said. “I think the reason we can be so happy is because we can communicate through everything and be honest with each other.”
