London: Keira Knightley has revealed that she's not scared of doing sex scenes.
The Never Let Me Go star said that getting nude for a role is not a big deal because everyone on set is often "respectful" and she always discusses what she is comfortable with beforehand.
"It's a consensual thing. You say what you're comfortable with and everybody's incredibly respectful," Contactmusic website quoted her as saying.
However, the 25-year-old actress was not so comfortable with auditioning as a child because she believed everyone thought she was "s**t".
"Some kids did karate, I went to auditions. They were humiliating. You walk in a room and they obviously think you're s**t.
"So you walk again. I mean the rejection level of anyone who does anything like that. It is quite a savage process," she told The Daily Telegraph.
