Robert Pattinson: 'Twilight sex scene was uncomfortable'

Robert Pattinson has revealed that his sex scene in The Twilight Saga: Breaking Dawn was "uncomfortable".

The 25-year-old confessed that he felt shy about being shirtless on camera because he knew his body could not compete with that of his co-star Taylor Lautner.

"Oh yes! I felt really uncomfortable," Pattinson told the German website TVMovie. "No, a fear had rather something to do with Taylor and his fantastic body. Jacob, as a werewolf, has bared all already in the last two films. And to be honest, I can't keep up with him."

However, he agreed with co-star Kristen Stewart's claims that the sex scene feels "real" and not "vampire-y", describing the sequence as "emotional".

"They're very emotional scenes," Pattinson said. "For the first time I felt like a human, not like a vampire."

The actor said earlier this month that he wanted his character to cry after the sex scene in question.

Twilight star Kellan Lutz recently revealed that he and Pattinson may be launching a clothing line together.
