“Married at First Sight” couples do everything at their own pace. While some couples have sex on their wedding night, others might be wondering why they haven’t kissed yet.

In an exclusive International Business Times clip, Kate Sisk confronts Luke Cuccurullo about their lack of lip-locking in “MAFS” Season 8, episode 4. “I just think it’s odd that you haven’t kissed me yet at all,” she says in the video above.

Though they shared a peck at the altar, Luke didn’t want to kiss Kate in front of everyone at the reception. The new Lifetime reality star felt like they were under pressure. Kate understands that, but they’ve had some private time since jetting off to their honeymoon. Still, Luke hasn’t tried to kiss her.

“We’re married now, and I’m committed to Luke,” Kate tells the camera in a confessional. “But at the same time, I got married at first sight because I want to be affectionate. Like, why haven’t you kissed me yet?”

Kate and Luke had a slightly awkward first meeting. When they met at the altar, Luke realized that they’d met before and Kate didn’t recognize him. After the ceremony, he revealed that he was an organizer at a recent speed-dating event. He’d even been emailing Kate to get her out to another event. They got off to an awkward start, but will they be able to get comfortable?

If kissing is still a problem, it’s safe to say Luke and Kate probably don’t have sex on their wedding night. Other couples might not have that problem, though.

“Married at First Sight” Season 8, episode 4 airs Tuesday at 9 p.m. EST on Lifetime.
