Michelle Money and Cody Sattler went on Marriage Boot Camp: Reality Stars for a reason -- but it clearly wasn't due to lack of a sex life.

The couple, who began dating on Bachelor in Paradise in Summer 2014, discuss the physical aspects of their relationship while playing with puppets in a new preview clip for Friday night's episode of Marriage Boot Camp.

"To be honest, I think our sex life is really healthy, and I don't know what else to do about it," Money, 35, says while wearing the puppet on her hand.

Sattler, a 29-year-old personal trainer who had competed on Andi Dorfman's season of The Bachelorette, then adds, "If we go a couple days without having sex, I almost start getting insecure that we're not as close."

The pair never got married and have had an on-again, off-again relationship. They split in December 2014 but reignited the flame of their romance shortly before appearing on Marriage Boot Camp.

Sattler then whispers to Money, "The sex in this house was really good, though," which elicits a surprised facial expression.

Money, a single mom and hair stylist who had competed on Season 15 of The Bachelor, also told marriage counselor Elizabeth Carroll things are "really good" for the couple between the sheets.

Money then says in a confessional, "Turns out, our sex life is actually a lot more healthy than our life outside of the bedroom."

Marriage Boot Camp: Reality Stars airs on Friday nights at 9PM ET/PT.
