New Delhi, Feb 7 (ANI): Dakota Johnson has admitted that she felt more pain while doing waxing for ' Fifty Shades of Grey' rather than her spanking scenes in the movie. Dakota, who will be playing Anastasia Steele in 'Fifty Shades', said that to look good in the wild sex scenes on Christian Grey's red room of pain she had to stay silky smooth and for this she underwent a lot of waxing than any woman should have, a leading daily reported. She described a scene with her co-star Jamie Dornan in which Christian Grey hurls Steele on to a bed in the middle of one steamy session, but it actually took multiple takes.
