"I don't have any problem doing anything," she told the magazine. "The secret is I have no shame."

The erotic film is based on E.L. James' wildly popular book of the same name and follows Anstasia (Johnson) as she is led into the world of S&M by the handsome billionaire Christian Grey (Jamie Dornan). "Reading the book, I found myself more interested in the ways they were breaking each other down emotionally than the sex scenes," Johnson, 24, admits. "I think there's a part of a woman that wants to be the thing that breaks a man down."
