Married at First Sight experts Pastor Calvin Roberson and Dr. Pepper Schwartz matched Lindy and Miguel, Krysten and Mitch, Alexis and Justin, Stacia and Nate, and Morgan and Binh.

After meeting at the altar, the show will feature pairs of strangers spending the next eight weeks embarking on a honeymoon, moving in together, and navigating the joys and struggles of daily life together.

And at the end of the experiment, Married at First Sight's five Season 15 couples will reach "Decision Day" and have to decide whether to remain married or decide to end their marriages and divorce.

On Day 3 of marriage, it marked the first official day of honeymoons for four couples.

Stacia said showering with Nate gave her a preview of what her husband is capable of and she could tell he's experienced and was intrigued by that.

"I definitely wanted to have sex with him, but I'm just trying to build the sexual tension for when the time does come. I don't want to have meaningless sex. I don't want to go off of a feeling from my body; I want to go off of a feeling from my heart and my soul," Stacia explained.

While Stacia and Nate took morning tequila shots together, Lindy said she got the best night sleep in three weeks. Lindy discovered Miguel snores, but there was sexual tension and they were very attracted to each other.

"There's a strong possibility that I could very well fall in love with Lindy," Miguel said.

Lindy shared how she was raised in a strict Christian household and was engaged at a very early age in college.

Lindy said it was fast and she moved in with the man, who hoped to start a family in Indiana. But Lindy wanted to have her independence and go to grad school. She lost her virginity to him and was the only man she had said "I love you" to.

Miguel shared how in past relationships, he often liked the woman but felt there was a missing component and he couldn't fall in love. Lindy therefore worried Miguel couldn't build those feelings for her, and she asked him to be honest with her and not blindside her.

Lindy thought life was a choice while Miguel were thought it was a feeling. Lindy felt Miguel kind of waved off or brushed off her concerns, saying "I don't know" or "we'll see" about falling in love with her, and she wished her husband would've given her more reassurance.

"I'm a real person right in front of him and I am his wife, and so it feels pretty callous and harsh, which is terrified when you're literally married and trying to start your life and fall in love with someone. Miguel reiterated how he couldn't "choose" to love someone.

Nate and Stacia went four wheeling together, but she got a little upset because he wasn't making sure she was okay or keeping an eye on her. She even lost him at times. Nate took a lot of photos and Stacia called him an "Instagram man," and she complained how he was doing his own thing the whole time and was a married man now.

Nate admitted he was still transitioning and trying to be more conscious of having someone by his side. She hoped this wouldn't become a "consistent issue" for them.

Meanwhile, Alexis and Justin rode horses on the beach. Justin said being so happy and comfortable in his marriage felt "surreal" and he felt like he needed to wake up from a great dream. And Alexis was feeling the same way.

"I'm usually cool, calm and collected and it takes me a while to fall for somebody, but I am losing control and that is pretty scary," Alexis told the cameras. It's just that look he gives me... I can tell he loves me by the way he looks at me."

Alexis apparently never felt that before in her life, but she also acknowledged how her emotions can fluctuate easily, from happy to sad, and it seemed her husband was trying to make her soft.

Mitch and Krysten returned to their element and went stand-up paddleboarding at the beach. The pair had a goofy and fun time, and Krysten called Mitch a good travel buddy. Krysten thought they had a similar sense of humor and told Mitch how she liked how he's passionate.

Krysten also said she appreciated how Mitch was teaching her ways to be better in terms of being responsible and saving the earth. However, Krysten admitted they were "moving slower" than she would've liked and Mitch still seemed uncomfortable with the whole experience.

Lindy and Miguel then went out to lunch together and learned there's a significant age different between them.

Miguel also opened up about having an identity crisis earlier in life  when his family moved to Puerto Rico. Miguel explained how he looked Puerto Rican but didn't speak Spanish and so he didn't feel like he fit in. He therefore "retreated" into a world of comic book and video games.

Miguel revealed how his mother suffers from Schizophrenia and left his family. Miguel said he understood the disease and the fact his mother cares for him, and he apparently has regrets in terms of how he had treated her when he was younger.

Miguel felt rejected but didn't understand why at the time, and Lindy said Miguel's compassion and strength were beautiful.

Lindy explained how her father had served her mother with divorce papers when Lindy was in eighth grade but she saw a healthy marriage when spending time with her high school boyfriend.

The pair agreed that arguing is healthy to a certain extent because it leads to understanding and compromise, and Lindy said she wanted to "break the cycle" in her family history. Miguel and Lindy both felt closer to each other as they shared more information.

"I need to protect myself, but I'm also falling for this man. I'm being vulnerable and that's scary, but he's being vulnerable with me, and so I'm going to meet him where he's at... My walls are going to start coming down," Lindy said in a confessional.

Mitch was then shown calling his brother Matt and explaining how he was putting tremendous pressure on himself in this experiment.

Mitch admitted Krysten is an awesome person and they have similar lifestyles, hobbies and goals -- and so he could definitely see why they were matched -- but he just wasn't "feeling that physical spark" with her.

Matt advised his brother to make his best effort in getting to know Krysten because Mitch didn't vow to be attracted to her on the first day. Matt also pointed out how Krysten is "cute" and so it was possible Mitch could develop feelings for her slowly over time.

"There's nothing wrong. She's a pretty amazing person, but I just can't pretend there's something inside of me that's not there. That's really what's happening," Mitch admitted.

Matt didn't want Mitch to make Krysten feel terrible, but he suggested a chat needed to be had.

Mitch cried and clearly felt overwhelmed, and he didn't even know how Krysten felt about him.

"This is way harder than I thought it was going to be," Mitch confessed in tears.

Back in San Diego on Morgan and Binh's wedding day, Morgan's nerves had disappeared and she seemed at ease while taking photos with Binh. The pair had a witty banter, and Morgan said she and Binh were starting to feel a connection and have intimacy.

"Something is definitely building. Something is stirring in the pot," Morgan shared in a confessional.

Binh could tell that Morgan is an alpha female, and so he told the cameras it was important to not get on her bad side.

Binh and Morgan's family members both asked the bride and groom how many children they'd like to have, and Binh noted how he really wants kids. Morgan, however, seemed unsure about having children, although Binh was assured Morgan may change her mind for the man she loves.

Morgan's bridesmaids also shared with Binh how Morgan can be "nasty" in the bedroom, which made him blush.

Morgan loved how Binh was warm, driven and nice, and Binh -- although a little scared of Morgan's kickboxing skills -- said he was grateful to have been matched with an ambitious, fun and cute bride.

Binh's parents had been together since 1975, and he hoped his marriage could turn out to be just as successful. The pair was optimistic they could build a connection, for sure.

That night in Mexico, Nate found out Stacia takes 90 to 120 minutes to get ready for a night out, which he thought was a lot, and Krysten was hoping for some affection on her dinner date with Mitch. She hoped for a hand grace or a sweet look, something other than a pinky promise to keep moving forward.

Mitch thanked Krysten for not rushing into things, but Krysten said she'd feel comfortable advancing their relationship in the physical and sexual department a little bit.

"I wish I felt a little more of that at this point," Mitch said. "It's just not quite there for me right now, and maybe I may not be feeling that physical attraction with you. And that's not easy for either of us. I'm the one with the issue here; it's not about you."

Krysten said that must have been hard for Mitch to get off his chest but she didn't understand it. Krysten said when Mitch looked at her, she could tell that he thought she was attractive.

Mitch explained how the physical part was moving slower for him, probably because they didn't know each other well. Krysten said she wasn't going to try to convince her husband that she's pretty and a catch, and Mitch agreed, saying he just hoped those feelings would come organically and he wasn't going to throw in the towel or cut and run.

"I'm committed to seeing this through with you, day by day," Mitch noted.

Krysten acknowledged how if she poked and prodded for specifics, it would probably just hurt her feelings. She was on the verge of tears but suggested an attraction may come for him with time and she'd remain hopeful for that.

"I feel confused. I just feel blindsided by him because his actions are showing me constantly that he is into me," Krysten told the cameras. "I'm just kind of hoping he is filled with anxiety and is in his head. I genuinely believe there is a chance he could get there on his own, but I'm not doing any convincing."

Krysten called this "the worst case scenario," her husband not being attracted to her, but she planned to continue being herself and just having fun. Krysten said they had great conversations and got along great, so she intended to focus on the positives.

Mitch also told Krysten that she is an amazing and beautiful person.

When Alexis and Justin enjoyed dinner together that night, Alexis admitted how she wanted Justin to contribute to her happiness but not be the main source of it in case they never worked out. Alexis wanted to be happy if she had to be on her own again, but she liked him a lot and said the feeling almost hurt her stomach.

"You're made for me, and I need you," Alexis told her husband.

Justin said he liked it when Alexis was emotional around him, and he looked forward to being the best version of himself for his wife. He said he'd do whatever it takes to keep her and have children with her.

When Alexis asked how Justin knew that he wanted to spend the rest of his life with her, Justin replied, "Because I love you... and I'm in love with you. It's not hard."

Alexis burst out laughing, and she said his love declaration scared her a little bit and almost made her want to walk away. Alexis told Justin that saying "I love you" in that moment was "too much" for her and she wasn't willing or going to say it back, but she seemed happy overall.

Alexis said if she loves someone, she loves him forever, and so she just wanted to be sure.

Justin then started to cry at the dinner table. He said if he got to design his perfect person, it would be Alexis -- and she had made it easy for him to be honest, open and totally himself. Justin said he didn't feel judged or insecure, and that feeling wasn't lust.

"I genuinely want to spend the rest of my life with you. They say 'love at first sight,' I think it's a thing, and I fell in love with you at the altar. I'm sorry if that scares you," Justin said.

"No it doesn't," Alexis noted.

Justin said he felt like Alexis loved him back through her actions and so he didn't even need her to say it or admit it. Justin just wanted Alexis to be aware of where he stood, and he noted, "When you're ready, I'm here."

During Stacia and Nate's first dinner out together, Stacia asked Nate about how he had filed for bankruptcy before. Nate explained how he and a friend funded a business with their own personal money and after putting blood, sweat and tears into it, the business failed and his credit got messed up, which was devastating for him.

Nate apparently moved to San Diego for a re-start, and Nate assured Stacia that all of that was in the past and his credit score had returned to normal. He said it wouldn't affect their relationship, but this was still a "yellow flag" for Stacia since finances are important to her.

Stacia said it would be beneficial to have a postnup in order to protect her assets, and she told the cameras that if Nate refused to sign one, it would be a dealbreaker and their marriage would be done. Nate said that was "fair," but he wanted Stacia to have faith in him.

Stacia thanked Nate for being so understanding, but Nate admitted it still hurt him because it was clear his wife didn't trust him. Nate intended on building that trust.

On the topic of kids, Stacia revealed how she wanted to have a baby in a year, and Nate confessed, "That's fast." Nate said he definitely wanted to have children sooner rather than later, but he envisioned having kids in two to three years.

"But it has to be with the right person," Nate blurted out.

"What do you mean 'the right person?' We're married!" Stacia responded, adding how starting a family was the most important thing to her in life at this point.

Before bed, Krysten and Mitch took shots together and munched on chocolate-covered strawberries. Krysten was being a good sport, but she was "absolutely frustrated" and confused. Krysten hoped Mitch would come to see their great dynamic as an attraction.

Mitch said a little social lubrication and Krysten's positive attitude was helping the situation, and he told the cameras that he felt rejuvenated and things were looking up.

The morning after Binh and Morgan slept in a bed together for the first time, Morgan surprised her husband with cupcakes and lit candles, and she gushed about her husband's buff body and how he looked "so good."

Binh said he and Morgan thought about having sex, and Morgan kept repeating out loud how she wanted to "f-ck" her husband. The couple then packing their belongings and headed to Mexico for their honeymoon.

On Day 4 of marriage for the other four couples, Nate said Stacia looked beautiful in the morning and is really sexy. He felt proud to have her as his wife, and Stacia said they matched each other's "swag."

Miguel was also enjoying his time with Lindy, and he said the couple was close to consummating their marriage. Miguel confirmed that his needs were being met, even though he wasn't having sex with his wife, but Lindy was the one pushing back.

Lindy said she had to work through religious guilt and shame for having pre-marital sex and so she appreciated Miguel being respectful and patient with her. Lindy shared how having sex was a really big deal to her and it meant two people becoming one.

Miguel, however, viewed sex as a form of affection and admitted sex is important to him. After a tense conversation, Miguel gave his wife a back massage by the pool.

Morgan and Binh then joined the other cast members in Puerto Vallarta, and they all hopped on a boat for a day of fun and sunshine. This excursion was a chance for all of them to bond.

Stacia shared with the other women how she planned to change her last name to Barnes. She didn't know her biological father, and so she was going to be proud of her new name, with no intention of changing it even if they got divorced.

"Nate is stuck with me forever and ever. I'll always be a Barnes," revealed Stacia, who had been longing to know that other side of her identity.

Miguel told the men how there was a little friction with Lindy because she wasn't ready to have sex yet. He said he was fine with having mediocre sex until things got better.

And Nate thought he and his wife were going to consummate their marriage by the end of the honeymoon because Stacia seemed really excited.

Binh was concerned Morgan may not want kids, and so he planned to ask her about that.

Mitch told the guys how he cuddled with Krysten and gave her a little kiss before bed, which actually got him "all fired up." And Krysten shared with the girls how she'd get into the nitty-gritty about her relationship the next day but she didn't want to kill the great mood on the boat.

"Mitch done something, and I want to know, 'What did Mitch do?'" Stacia vented.

After the boat trip, Alexis said everyone seemed to be in the joyful newlywed stage except for Mitch and Krysten.

Mitch and Krysten then received professional massages, and Mitch told the cameras how a fire can always be stoked and his interaction with Krysten in the bedroom gave him some hope.

Krysten was happy Mitch had made a move, and she told him that he's a good kisser. Krysten told Mitch that she didn't go all the way with him because she was feeling a little insecure and so she didn't want that night to be their "moment."

Krysten suggested that Mitch could compliment her more, even if it's just to tell her that she's funny or something, and Mitch totally agreed. Krysten wanted to feel wanted and appreciated, and she asked Mitch to keep progressing things.

"If we do get to Decision Day and I don't have sex from you or an 'I love you' from you, I will ask for a divorce," Krysten clarified for her husband.
