During Wednesday night's episode of Married at First Sight: Unfiltered hosted by Jamie Otis, Iris watched back a Season 9 clip of Keith expressing to Pastor Calvin Roberson how he wasn't quite sexually attracted to Iris yet due to her alleged lack of sexual maturity.
The 6'9" former professional basketball player then shared, "I kind of struggle with it just because certain places are difficult for me because of my height, so just for logistic reasons, the bed is usually the best place."
In the latest episode of Married at First Sight, Keith questioned Iris' sexual maturity again when they were asked by the experts to reveal a secret to each other.
Instead of sharing something deep, sexy or personal, Iris told Keith that she had once swallowed a quarter on a school bus and was really embarrassed about it.
Keith couldn't believe that's what Iris chose to share, and he didn't know what to think at the time.
