Jennifer Lopez and Ryan Guzman had sizzling chemistry during the filming of their 2015 movie, The Boy Next Door.

In a recent interview with Cosmopolitan, Guzman spilled the beans on how he prepared for their intimate scene in the movie.

Guzman revealed that to avoid an “accident” while filming that racy scene, he wore something called a “d*ck tie.”

In the movie, Lopez played Claire Peterson, a woman who was feeling insecure after her divorce.

Claire was in her late 30s to early 40s and craved validation.

Noah Sandborn, her much younger neighbor, gave her attention, and she ended up sleeping with him.

This move complicated her personal and work life.

Guzman portrayed Noah Sandborn, and he had to make sure the s** scene between him and J.Lo looked realistic.

To achieve this, both actors had to wear little clothing.

Guzman had to wear a sock and something he calls a “d*ck tie” around his nether regions, so he wouldn’t have an “accident” while interacting with Lopez.

According to Guzman, a “d*ck tie” is an elastic thing on a sock, made as tight as possible, to restrict blood flow.

It holds onto the man’s private parts so that the sock doesn’t come off during the scene.

He says he was nervous about doing the scene with Lopez, but she helped ease his anxiety.

“She was the one who kept me at ease,” Guzman said.

“She talked me down.

She said, ‘We’re going to do this [and] we’re going to do that.

Everything is going to be fun.

You’re going to have fun.’ It was.”

However, the nerves were still intense for both actors.

They ended up laughing so much during the intimate scene that the director had to tell them to stop and compose themselves.

Guzman said when he looked at Lopez, she started laughing, and then he started laughing too.

“Finally, [Director Rob Cohen] was like after five minutes, ‘Guys, let’s get back to work.’” Guzman tells E!

During an interview with Ryan Seacrest, J.Lo said that she wouldn’t be offended if her co-star didn’t get excited during the racy scene.

“I don’t care,” she tells Seacrest.

“Let’s just get the scene over with.

I get mine at home; I’m good.

I’m not here for that; I like keeping it professional.

I don’t need it to get messy at work.”

While Lopez kept it professional, Guzman revealed that he was a bundle of nerves throughout the scene.

It was his first time doing a s** scene on camera, and he wasn’t sure how he’d handle it.

However, thanks to Lopez’s reassurance and the “d*ck tie,” the scene came out perfectly.

In conclusion, Jennifer Lopez and Ryan Guzman shared great chemistry during the filming of The Boy Next Door, but it wasn’t all fun and games.

Guzman had to wear a “d*ck tie” to avoid any accidents while filming the racy scene.

Despite the nerves and giggles, the scene turned out great, thanks to their professionalism and preparation.
