Jennifer Lopez put Ryan Guzman at ease during their sex scenes for 'The Boy Next Door'.

The 27-year-old actor - who stars opposite the 'On The Floor' hitmaker in the thriller - admitted he was incredibly nervous ahead of their intimate scenes.

He shared: ''I finally had to go to her and say, 'I'm really nervous about this, this is the first time I'm getting naked in front of a bunch of people I don't really know.'

''I have to wear this little sock on my, you know, and it was pretty emasculating.''

Jennifer, 45, though, was on hand to help ease his nerves.

He added to ''She pulled me off to the side and told me, 'It's a part of the film industry and we're just telling a story. We have to tell it to the best of our ability.'

''It had to have so much intensity and so much passion that the audience felt it. We wanted to make it memorable and we did that.''

Ryan also admitted that the whole scene was ''awkward'' but he knew it was important because it was a big part of his character's development.

He said previously: ''Any intimacy that you think might be in the scene isn't there. It's all choreographed and that's our part as actors to develop that look of passion.

''We were so focused on making that scene so passionate, because without that scene, you have no movie. My character never would've done the things he did without having had that beautiful, life-changing, sensual, intimate, sexual experience like that.''
