"Fifty Shades of Grey" stars admit what it's really like filming those racy sex scenes

The "Fifty Shades of Grey" trailer, released Thursday morning, gave fans of the best-selling E.L. James book series a glimpse into what they can expect from the film adaptation.

Red room of pain? Check. Christian Grey (Jamie Dornan) looking smoking hot in a suit? Check. Lots of smoking hot sex scenes? Double check!

But, how did Dakota Johnson, who plays Anastasia Steele, and Dornan feel about filming those racy scenes?

"It's not like a romantic situation its more technical and coordinated," she told "Today" show host Savannah Guthrie. "It's more of a task."

Ouch!

While we know what Johnson thought about the scenes with her clothes off in the film, her co-star had more trouble feeling comfortable scenes with his clothes on. Particularly, the ones where he is wearing a suit!

"A lot of that work was done in the gym and with costume. We didn't talk about particulars of the way he would move," the hunky actor told recently told Interview magazine. "But I'm quite awkward in a suit because I don't have an opportunity to wear a suit very often, and this is a guy who lives in a suit -- the best suit. That has to have an effect."
