Amy Schumer revealed X-rated 'major regret' about John Cena sex scene where she said he was ‘inside her’

Let’s be honest; John Cena has played his fair share of random characters in movies.

From a less than a minute-long cameo as a merman in Barbie, to an impersonator in Ricky Stanicky, the 47-year-old has had some more memorable performances.

Like the time he played Steven in 2015’s Trainwreck alongside Amy Schumer.

And the comedian revealed she had an X-rated ‘major regret’ about her sex scene with Cena where she said he was ‘inside her’.

While Cena has admitted he didn't tell his fiancée about the comedic steamy moment in the film, and describing it as pretty ‘awkward’, Schumer was however ‘very into it’.

In Trainwreck, Schumer is a bit of a commitment-phobe who doesn’t think she can handle monogamy before she meets that guy.

But before that, one of her partners includes gym-rat Steven, who she strips down with as he promises to ‘fill you with protein’ and ‘put my green drink in you’.

During an Aussie chat show, Schumer was asked how she kept a straight face as Cena’s modesty was only just about protected.

“Because he was actually inside me. Who am I to stop him?” she joked.

And speaking during press interviews around the release, she added: “It’s a whole universe, that butt… it’s not even human.

“It felt like having a refrigerator on top of me.”

And to MTV Australia, Schumer admitted: “I think it was probably harder for him. He had to, like, do something. I just did what I usually do when I have sex. Just lay there, so yeah.”

She then went on to reveal a bit of a regret over the scene; she ‘didn’t get to feel his balls’.

“It’s a major regret of mine, major regret,” the star joked.

During an appearance on the Club Shay Shay podcast, Cena explained how awkward it is to film a sex scene.

Pointing at the podcast crew during the recording, he said: “This is the thing — right now, you guys at home think it's just us. No, there's a whole f**king world back here,” before adding there were even more on set of the film.

He continued: “There are so many people you need to make a movie. There is nothing intimate about it. Nothing.

“So it's real embarrassing, and on top of that, to do a comedic sex scene when you're making fun of yourself.”

And while he described the awkwardness, Schumer joked on Instagram: “John, how dare you?”

Sharing a broken heart in the caption, she said: “That sex scene meant a lot to me, and I was, like, very into it. And I’m in love with you.”
