Smooching your hubby in the street before planting a kiss on your best friend and then giving her husband a peck for good measure is obviously going leave onlookers raising their eyebrows.
It's like Wife Swap on steroids, except this freaky foursome all join in on the fun and are all great pals.
Take a look at a day in their life here:
Katy and her husband, porn star Rob Oz, say they don't mind the disapproving stares from people who spot them swapping snogging partners - in fact, their relationship is a case of the more, the merrier - especially in the bedroom.

The triathlete struck up a whirlwind romance with the adult star after meeting him in Australia, despite concerns voiced by her family were back in the UK. Six weeks later, they got engaged.
Their journey through married life hasn't followed the conventional route though, as you can imagine; if anything, it's quite the opposite.
Katy and Rob have taken their eccentric relationship to a whole new level by inviting their best friends, Dee and Will, to join them between the sheets.
Both couples appeared on the Truly series Love Don't Judge, which shines a light on the struggles people with unconventional dating lives face and how they 'get judged every day because of who they fell in love with'.

Explaining how their four-way romance began, Katy said: "When we met Will and Dee the relationship kind of flowed from the start. It was our first swingers couple that we engaged with."
The ladies have no qualms about sharing their husbands with one another, as after all, they're best friends, right?
Katy, Rob, Will and Dee are now in a polyamorous relationship together, while also making a killing sharing their X-rated content online.
Dee chimed in: "We sleep with Katy separately, we sleep with Rob separately, we sleep with them together.
"We have other people come over, like we've had big orgies together."

The women share a particularly close connection and described their situation as 'like having a sister', while the lads describe their dynamic as a 'bromance'.
"But someone you can explore sexually with and learn more about yourself in that realm as well," Katy added.
These lot are anything but shy and don't mind putting on a show in public either - in fact, they revel in watching peoples outraged reactions when they all start kissing one another.
Katy laughed: "It does confuse people when we're out. We'd be kissing and then we'd switch... so I'd be kissing Will and Dee would be kissing Rob and people are like - what did I just watch?"

Dee said muscling in on her bestie's marriage is 'probably one of the best choices we've made in life', but made it clear it's a 'we thing, not a me thing' - which was seconded by Rob, who added: "The four of us are like one organism."
Social media trolls have obviously given their two pennies on their relationship though and bombard the foursome with hateful comments about their sexual set-up and how they are at 'putting their health at risk'.
They'd really have a heart attack if they heard that Katy and Rob regularly introduce other characters into their bedroom antics on top of Will and Dee then.
The latter prefer to 'do everything together', while the porn star will 'pick up guys' for his wife and bring them home.

Recalling one of his matchmaking triumphs, Katy said: "Rob could see that I liked this guy so we all came home together and he shook his hand and said 'Go have fun with my wife'.
"I mean - if that isn't a man..."
He says his spouse can get 'wined and dined as regular as she wants', which is certainly giving Will and Dee tips for how to perfect married life when they get hitched next year.
The pair said they will celebrate their nuptials with a 'swingers after party' - well, what else did you expect?
