What Jamie Dornan Had to Do for 'Fifty Shades of Grey' Sex Scenes

What he compared his manhood to during filming.

"Your dignity is intact as much as it's all tucked away in a little flesh-coloured bag," he told British GQ for its February issue.

He continued, "As a guy, you put all your essentials in a little bag and you tie it up like a little bag of grapes and it's tucked away. It's quite a peculiar thing to do every day."

After researching for the role of Christian Grey by going to sex dungeons, Dornan said he is okay with people who are into bondage and BDSM.

Dornan, who married Amelia Warner in 2013 and had a baby with her last year, also gushed about his "understanding" wife.

"I'm married to the most understanding person I've ever met. I have a baby. I think those are good things that stand me in decent stead going into whatever it is," he added.
