During the February 2 episode of Married at First Sight: Afterparty, Lindsey and her MAFS14 co-star Katina Goode watched back a Season 14 clip of Lindsey and Mark having a "romantic" dinner during their honeymoon in San Juan, Puerto Rico.
"I don't want to get too, too lovey dovey because we literally just met and there are so many things that are going on -- and it has to flow organically," Mark tells Lindsey in the clip.
"If you want me to be less then you need to stop f-cking clogging the toilet and farting in bed. Like, if you want to be less, let's stop that, okay?" Lindsey snaps in reply.
On Afterparty, Lindsey confirmed with host Keshia Knight Pulliam that she was "very upset" with him that night.
"He kept telling me, 'You are going to feel romance tonight. You have been so good to me, I am going to blow your mind.' So he's built up this great, romantic dinner," Lindsey shared.
"I just got a complete 180 from him, and Mark is pretty intense in the beginning, like, 'Do you want me to poop with the door open or closed? Be careful I might get poop dust on my underwear!'"
Lindsey said Mark was "really full-on" from the get-go, which kind of set the pace for their relationship in her mind.
"I'm definitely not somebody who would say it first and I'm usually [like Steve Moy], where they say, 'I love you,' and then I'm like, 'Thanks! I'll get back to you in three to five business days,'" she joked.
Mark explained on last week's Season 14 episode of Married at First Sight how he and Lindsey had a lot in common but her fighting with other cast members affected their opportunities to bond and get to know each other better.
"It's like I can't breathe. I'm just trying to digest it," Mark said, adding how he didn't want to rush things. "I want to go slow in the process."
Mark said he felt like he was drowning in the chaos Lindsey sparked, and he seemed to want to slow down the physical aspect of their relationship -- without coming right out and saying they had consummated their marriage already.
Lindsey pointed out how Mark had initiated the intimacy to begin with, and she said, "I can pull back, but I pull way back. I pull all the way back. There is no in between for me."
In addition to her shocking farting and pooping comments, Lindsey complained to Mark that he was also chewing with his mouth open and not holding anything back from her.
Lindsey found herself frustrated and mad, but Mark said he just didn't want Lindsey to operate with the highest of energy at all times and needed more time to process things.
Lindsey said Mark had "really screwed up." She didn't want to talk to Mark or work things out in the moment, and she called him "a stupid idiot" for not knowing how his words would affect their future together.
Married at First Sight's fourteenth season, which currently airs on Wednesday nights at 8PM ET/PT on Lifetime, also stars Steve and Noi Phommasak, Katina and Olajuwon Dickerson, Michael Morency and Jasmina Outar, and Alyssa Ellman and Chris Collette.
