"I can't be concerned when she is going to want to have sex with me right now. Because at this point, I'm still not ready for that either," Keith told Married at First Sight: Unfiltered host Jamie Otis on the discussion show's Wednesday night broadcast.
"That's really tough," he replied. "I mean how do you even begin to sort that out?"
"I think for me, I think communication is the first key -- for Keith, you got to ask, 'Iris, do you want to lose your virginity. I know we're married, but are you ready to take that step.' And she's got to be comfortable with that."
The Unfiltered host then asked Keith if he'd ever asked Iris that question, and Keith acknowledged the couple may not even end up ever having sex before "Decision Day," the eight-week mark in which each Married at First Sight Season 9 couple must decide whether they'd like to stay married or get a divorce.
"We talked about expectations, and she let me know it just really depends how fast we get comfortable with each other," Keith said.
"It may take two weeks, three weeks -- it may take longer than the eight weeks we have. But for me, I really just wanted to put my best foot forward and trust the experts to do their thing too."
Earlier in the broadcast, the Married at First Sight: Unfiltered host had also asked Keith specifically how intimate Keith and Iris have gotten.
"Keith, how physical have you two become? Like have you held hands? Have you hugged? Have you kissed?" Jamie asked.
