Robert Brown|Summer House's Lindsay Hubbard and Carl Radke Only Had Sex This Often Before Breakup

Lindsay Hubbard and Robert BrownCarl Radke weren't necessarily hot and heavy for each other before they called off their engagement.

In fact, during Summer House's March 21 episode, Lindsay made a shocking confession about her and Carl's sex life just several months before they broke up last August.

"He's not a very sexual person," the publicist admitted to costars Paige DeSorbo and Amanda Batula, to which Paige replied, "I feel like you're a very sexual person in general. Even in conversation you're like flirty, you'll talk about sex. He's more reserved."

But when Paige asked her Bravo costar point-blank "how often are you having sex?" Lindsay's answer shocked the women.

"Like once every couple of weeks," the 37-year-old shared before noting of Paige and boyfriend Craig Conover, "You're probably having sex with your long-distance boyfriend more than me."

In a confessional, Paige revealed she believed Lindsay was actually exaggerating the frequency of her and Carl's intimacy.

"I feel like when people talk about their sex life, they lie a little," the Giggly Squad podcast cohost said. "So if she's telling us they don't have sex for two weeks at a time, that's six weeks. And I don't make the rules, but that's alarming."

The candid discussion continued with Amanda prodding, "But when you guys have sex it's good?" to which Lindsay confirmed, "It's, like, such good sex."

While Amanda encouraged Lindsay, "It's like you just have to do it again to remember," Paige noted, "You're almost like too in your head about it now."

As Amanda stated, "You guys enjoy it when you do it, so just do it."

But that's easier said than done, as Lindsay revealed Carl "doesn't even initiate" sex with her to begin with.

Exactly two weeks after the split news came to light, Lindsay broke her silence and revealed she's "heartbroken" and humiliated" with how Carl ended things.

"My trust has been betrayed, and coming to terms with that has been difficult for me," she wrote on Instagram Sept. 14. "This was not my decision, and I do not agree with quitting a relationship (at this level) without trying everything possible first. I have spent the last couple of weeks finding my own closure and peace. I am forever grateful to my best friends who have not left my side, and have been picking up the pieces of my heart and life every day from the fallout."
