How John Cena's Naked 'Big Butt' Sex Scene Caused Problems in Bedroom for Nikki Bella

During Sunday's "Total Bellas," Nikki Bella voiced her doubts about her relationship with John Cena and the "deep feelings" that have started to surface.

From seeing her fiance's "big butt" onscreen (and how it affected her ability to masturbate) to how much it bothers Nikki that her then-future-husband did not like to travel, Sunday's episode featured plenty of pre-wedding drama.

While arriving at her Parisian bachelorette getaway with her girls, Nikki shared her concerns to one of her friends.

"This past week he just thought, because he had the week off in San Diego, I was gonna take a week off," Nikki said. "I'm like busier than ever. So he's like, 'I was really lonely.' I saw him every morning and every evening. Emails don't end just because you want my time. It's really tough."

"It's funny because, the closer and closer I'm getting to the wedding, the more of these deep feelings that I've had over the past six years just are coming to the surface," she added in a confessional.

Nikki told her friend that she feels very "connected" to Paris, but John doesn't really enjoy traveling unless it's for work purposes.

"That's why it's good you had a few days here, even by yourself, just to like rest and do exactly what you want to do," her friend said back to here.

Besides for John's busy schedule, it seems like his acting gigs might be affecting their sex life.

"Imagine watching your man do a sex scene and have the whole world see his big butt," Nikki said at dinner. "You know you get visuals. I swear I couldn't masturbate forever because I just think of the sex scene."

The pro wrestler's "big butt" featured prominently in at least two of his films. While we can't be sure, Nikki was most likely referring to John's sex scene with Amy Schumer in "Trainwreck." However, his booty was also shown in his most recent film "Blockers" when his character participated in beer butt chugging contest.

Since Nikki had her worries on her mind, her bachelorette party was feeling more like a girl's trip and not the single send off she was expecting.

"But it's funny because like even just this bachelorette getaway it's not everything I thought it was going to feel like," Nikki said in confessional. "I think because John has been so absent wedding planning that anything that is wedding related it just, it almost doesn't feel real like it's really happening. For me it almost feels more like a girl's trip than a bachelorette trip."

While Facetiming, John tried to cheer up his bride-to-be, who he definitely could see was down.

"I'm tired of seeing you tired," he said to her. "Fire this shit up and get your bachelorette on." So that's exactly what she did. Well, kind of.

Nikki arrived three days early to the city of love to have her "Sex and the City" moment and was clear she wanted a classy bachelorette party. However, since the WWE star wasn't in the best mood at first, it seemed that the trip wasn't going as planned. So it was time for her twin and maid of honor, Brie Bella to step in to turn this "boring" trip into something "crazy."

Brie suggested that Nikki participate in some dares, such as scaring the waiter at dinner and talking to strangers as if they were John. Nikki went along with it, but wasn't having too much fun.

"I hate this shit, I never want to be a bachelorette again," she said.

Since Brie couldn't stand to see "poo poo" face another night, she thought of an even better idea: a masquerade ball, in which the girls would all get styled in gorgeous gowns and masks.

Nikki loved the idea and said she was "down." However, she didn't think Brie could pull it off in time. But Brie was determinnd to turn the trip around.

"It's crazy because my sister lately has really kind of shocked me," she said in a confessional. "I feel like I'm looking at my sister and I'm not seeing the same Nicole I saw a year ago. I feel like now I need to step up. I need to really change her mood, so I want to make sure it's exactly what my sister wants and hopefully I nail everything."

When the stylist arrived, there seemed to have been a "miscommunication" as she brought lingerie, "bedazzled titty tassels," collars, and whips, instead of the gowns Brie had asked for.

Now Brie and her sister-in-law Lauren have to go out and purchase dresses themselves. We will have to see if it all works out during part 2 of Nikki's bachelorette party when "Total Bellas" airs next Sunday at 9 p.m. EST on E!
