Let’s talk about sex.

Nick Viall’s sexcapades — or lack thereof this season — became a prominent talking point between the “Bachelor” and his ex, Andi Dorfman, on Monday’s episode.

Ahead of the rose ceremony, the one-time “Bachelorette” made a surprise visit to Nick’s hotel room, where they took an unexpected trip down memory lane.

“Andi is the last person I’d ever thought I’d see. I’m really curious why Andi’s here right before a rose ceremony,” Nick shares.

“The last time Andi knocked on my hotel door, she broke up with me,” he continues.

Two years removed from the breakup, Andi hopes she and Nick can move beyond their past and focus on his future — more specifically, the Fantasy Suites.

“I think if you see a potential for that girl, getting down on one knee, if you two agree to take it to the next level and to be intimate,” Andi says. “You’re an adult.”

With four girls remaining, Nick also lets it slip that an engagement may not be in his immediate future.

“I’m not going to get engaged just because I’m the ‘Bachelor,’” he says.

Though a happily-ever-after is Nick’s ultimate goal, he first has to eliminate one woman before venturing on to Finland and the Fantasy Suites. And unfortunately for Corinne, she won’t be stamping her passport.

Not that there’s much time to mourn the loss of Corinne as Nick kicks off his stay in Finland with a romantic date with Raven Gates. After touring the country via helicopter, the couple gets cozy in a bar before heading off to a secluded cabin for a candlelit dinner.

“Tonight’s the big night. Fantasy suite and everything today,” Raven explains. “My fears are saying ‘I love you’ and having sex with him at the end of the night, because being physical and emotional can lead to a double heartbreak.”

While Raven believes she fell in love with Nick on their first date, after telling him those three little words, Raven believes their future is well within reach.

“I feel relief, seeing Nick’s reaction, I believe he does love me too,” Raven says. “My heart is beating really fast. Nick makes me feel extremely safe.”

But before they venture to the Fantasy Suite, Raven lays down the ground rules for Nick, including an admission he didn’t see coming.

“I’ve only been sexually active with one other man. Sex is a big deal to me,” Raven reveals in her confessional.

Face to face with Nick, Raven shares another sex secret of her past.

“My last boyfriend, my ex, never made me orgasm,” Raven reveals to Nick. “Lost for words?”

Answer: Yes.

“Was not expecting that,” Nick replies.

Though Nick assures Raven their night together is more about the strength of their relationship, he also questions if sleeping with his girlfriends will provide the clarity he longs for.

“Coming into this week, I was quite nervous in the sense that I wanted to have a clear head about it,” Nick explains. “Not sleeping with the women, I quite honestly don’t know how I’m going to approach this.”

While both Nick and Raven enter the cabin, it’s unclear if they spend their night simply watching the Northern Lights.

With two other Fantasy Suite dates up next, Nick’s journey to his potential Ms. Right is about to get a lot more complicated.
