90 Day Fiancé‘s Josko Luketin shocked Vanja Grbic by sharing personal details about their sex life during the 90 Day Fiancé: Before the 90 Days reunion.

In a teaser clip for part 3 of the tell-all on Sunday, January 26, shared by Entertainment Tonight, Vanja, 41, broke down in tears while admitting why she was upset with Josko. “It’s just being intimate with somebody for me is a big deal and the fact that he got that from me ….” she began.

While Vanja wasn’t sure that she wished she could have taken “back” their intimate moments together, she said that she wished they never had sex.

After several of their costars agreed that it seemed like Josko “used” Vanja for physical intimacy, he said that he “completely disagreed” with the claims. “When I was coming to Orlando, we were just … extending on what we built back in Croatia and I didn’t come with the thoughts to break up with her or to end the relationship,” he said.

Josko added that his child grew upset when he left his native Croatia to visit Vanja in Florida, which ultimately led to his decision to end their romance. “I didn’t come to Orlando with the thought, ‘Oh, I’m gonna have sex and then I’m gonna break up with her,’” he continued. “That’s completely unrealistic.”

He then shared that he and Vanja were not sexually intimate during her trip to Croatia, though they started having sex when he visited her in Orlando. In fact, he added that they would sleep together “three or four times a day.”

“Sex-wise, I don’t know if it’s a glass half-empty or glass half-full. Either I’m too big for her or she’s too small for me,” Josko continued, adding that they did “one or two positions all the time.”

Vanja appeared uncomfortable as Josko shared the intimate details of their sex life, and she eventually cut him off to sarcastically call his behavior “classy.”

“Very unnecessary,” she continued. “I wasn’t going to go here because this was very emotional for me, but I’m gonna share it now that you shared that. Without my knowledge, he took a video of us while we were being intimate.”

The clip concluded before Josko could react to the allegations, though several of their costars gasped in response to Vanja’s claims.

Fans learned of trouble in their romance during the January 5 episode when Vanja told the cameras that Josko “all of a sudden” stopped calling her after his trip to Florida. She eventually asked him for “consistency in their communication moving forward,” and he responded by calling her “needy.”

“And I don’t like this. Click and he hung up on me. So I’m thinking he’s going to call me back and apologize, he doesn’t,” she said in a confessional. “Finally five days later, I get a text message and he’s like, ‘Oh can we talk.”

Following their conversation, Vanja explained that Josko ended their relationship because he believed she didn’t have “motherly instincts.”

“Josko broke it off with me just a few weeks after his trip, came as a complete shock,” she said. “And I thought because we formed this incredible connection that he would call me the next day apologizing, but I haven’t heard from him since.”
