Jade Roper has revealed her husband Tanner Tolbert isn't generous in the bedroom.

In a sneak peek for the next episode of Marriage Boot Camp: Reality Stars obtained by Us Weekly, the participants play a game of "Truth or Dare" and Roper picks a Truth card that reads, "Would you rather give or receive oral sex?"

Without hesitation, Roper announces to the whole group sitting before her, "Tanner never does. Never ever."

"Very rarely," Tolbert confirms nonchalantly.

"I have to beg," Roper insists.

Tolbert is up next, picks a Truth card as well, and is asked to answer the following question: "Have you had sex in a public place?"

Tolbert then reveals, "Yeah, I have -- but it wasn't with Jade."

"I worked for the KU football team and had keys to the stadium," he elaborates without being asked to. "We went and did it on the 50-yard line."

Once Tolbert returns to the group and sits next to his wife on the grass, he asks her privately, "Should we go and do it somewhere public?" Roper replies flatly, "No."

Tolbert uncomfortably laughs off the situation by suggesting, "I know. It's, like, something you do when you're younger, you know?"

"I don't know," Roper argues. "I don't think so."

In a subsequent confessional, Roper tells Tolbert in front of the cameras, "You wanted to brag."

"I was asked if I had sex in a public place, and I said, 'Yeah,'" Tolbert says.

"But the exercise is about..." Roper begins, before Tolbert interjects, "Jade, I should have just said no."

"Yes," Roper agrees.

Marriage Boot Camp: Reality Stars has shown the Bachelor in Paradise couple appearing to struggle in their relationship throughout the season.

Issues that have been addressed include Tolbert complaining his wife doesn't carry her weight in their marriage, Roper seeking more emotion from and a deeper connection with her life partner, and lack of communication in general. Now, their sex life can be added into the mix.

Roper and Tolbert tied the knot in a televised January 2016 wedding after falling in love and getting engaged on Bachelor in Paradise's second season, which aired in Summer 2015.

Prior to BiP, Roper competed for Chris Soules on The Bachelor and Tolbert took a shot at finding love with Kaitlyn Bristowe on The Bachelorette.

Marriage Boot Camp: Reality Stars is set to air its next episode Friday, November 11 at 9PM ET/PT on WE tv.
