On Tuesday night's episode of FYI's reality TV series "Married at First Sight," it was three weeks since the couples each met as strangers at the altar. The couples each have struggled with intimacy issues and expert sexologist Dr. Logan Levkoff gave all of them a fishbowl full of questions as a homework assignment meant to bring the couples closer together. The questions seemed to help the couples break down barriers, but one wife still won't allow her husband to kiss her.

Tres Russell & Vanessa Nelson

Even though they were the first of the three couples to consummate their marriage, Russell and Nelson still faced problems in their marriage. Nelson struggled with her own trust issues and had trouble adjusting to Russell's demanding work schedule and Russell said the lack of communication was his biggest concern. The couple did well with Levkoff's fishbowl, which made Russell appreciate his wife even more than he did before. "I can see this working," Russell said in his on-camera interview. "I think I'm falling in love with her. It feels so good to say that."

Neil Bowlus & Samantha Role

Role has started to warm up to her husband and Bowlus started to do the same, so much that the couple has made a significant amount of progress since they met on their wedding night. Role said that even though she didn't feel attracted to Bowlus at first, attraction is something that grows for her and she's been able to move past it. During their session with Levkoff, the couple was able to be honest about their needs and wants from their relationship and even though the fishbowl exercise made Role uncomfortable, she still participated. "I'm starting to get in the vibe of a married couple," she said in her on-camera interview, "it just sucks it took this long."

David Norton & Ashley Doherty

Doherty struggled the most out of the three wives with intimacy and feeling comfortable with her husband and Norton has been patient, but his patience seemed to be wearing thin. He expressed his frustration with the lack of intimacy and communication in their marriage during Levkoff's visit. He was hopeful that the fishbowl assignment would help Doherty open up to him, but she still remained cold and emotionally detached from her husband during the exercise. Doherty reached out to her friend and bridesmaid Ashley, who suggested that they make it a point to go out on more date nights to spend more time with each other. Nelson took Doherty on a nighttime ride on the SkyView Atlanta Ferris wheel and the couple laughed and seemed to have fun, but when Nelson plucked up the courage to lean and kiss his wife for the first time, she turned her head - forcing Nelson to kiss her cheek instead. "Why won't my wife kiss me?" Nelson asked in his on-camera interview. "I know there's more to it. I want to fix it, but you can't fix something if half the partnership doesn't know what's going on."
