"I went there, they offered me a beer, and they did...whatever they were into. I saw a dominant with one of his two submissives," Dornan, 32, told UK magazine.

"... It was an interesting evening. Then going back to my wife and newborn baby afterwards... I had a long shower before touching either of them."

The film, based on E L James novel of the same name, stars Dakota Johnson as Anastasia Steele. It will hit theatres on February 13.
