Thus far on Married at First Sight, Sean Varricchio and Davina Kullar have had a tough time connecting on an intimate level throughout their marriage, but that could all change after some “homework” assigned by the show’s sexologist.

In this week’s episode, the newlyweds sip on red wine while playing Dr. Logan Levkoff’s “fishbowl game” to try and spark intimacy in their relationship.

“If Davina stayed positive Davina and fun Davina at all times, could I see more than a friendship building with her? Yes, I do believe that,” says Varricchio in a clip from the episode shared exclusively with PEOPLE.

Pulling a question from the bowl asking the couple to describe the “most unusual thing someone has asked you to do in bed,” Varricchio immediately recalls a partner who asked him to “suck on their toes.”

“That’s disgusting. It’s not even sexy,” he says, grimacing. Showing she’s game for anything, Kullar takes up her husband’s dare to suck on her own toe, much to his chagrin.

“It’s my toe! I love my toe,” says Kullar, laughing. “I can never turn down a dare.”

Married at First Sight airs Tuesdays (9 p.m. ET) on A&E.
