'Fifty Shades of Grey' is one of the most-anticipated films in 2015, but it seems that the two lead actors playing the roles of Anastasia Steele and Christian Grey are having a tough time filming the sex scenes.

It is reported that Jamie Dornan, the actor playing Christian Grey, is tired of the nude scenes he has to do and that it makes him 'sick.'

In an interview with British Vogue magazine, Dornan revealed that he is not interested in reprising his role as Christian Grey in the sequels because of the intense nudity that he had to go through in front of the camera, as reported by Cosmopolitan.

The sequels are inevitable, since there are three books that complete the series with others being called 'Fifty Shades Darker,' and 'Fifty Shades Freed.'

Sons of Anarchy actor Charlie Hunnam dropped out of playing Christian Grey before Dornan took the role, and spoke about the integrity that lies on playing such a provocative role.

"Anybody that knows the process of actors with integrity going about choosing roles knew that all of those questions would have been answered in the very first meeting and that had any of that actually been the case, I would have not gotten myself in the situation in the first place," Hunnam said in an interview with Entertainment Weekly.

Meanwhile actress Dakota Johnson, who plays Anastasia Steele, feels that her sex scenes in the movie are too kinky for her family to witness.

According to reports Johnson has apparently "banned" her family from seeing the movie once it premieres, and that she only let her sister know what's going on on the set of Fifty Shades of Grey.
