Pattinson 'uncomfortable with sex scenes'

Robert Pattinson has confessed that he found it uncomfortable filming gay sex scenes for his upcoming movie Little Ashes.

The Twilight star plays a young Salvador Dalí in the forthcoming period drama, which details the artist's pre-fame relationships with director Luis Buñuel, and poet Federico García Lorca.

Speaking to GQ, he said: "In a lot of ways, I was kind of crossing lines of what I thought I was comfortable doing. I had to do all this naked stuff.

"Here I am, with Javier [Beltrán], who plays Lorca, doing an extremely hardcore sex scene, where I have a nervous breakdown afterward. And because we’re both straight, what we were doing seemed kind of ridiculous."

The 22-year-old, who admitted that he took the role before the success of Twilight, explained that he found it awkward filming the explicit scenes with the crew watching.

"There were all these Spanish electricians giggling to themselves," he revealed, adding: "And you know, I haven’t even done a sex scene with a girl, in my whole career."

Little Ashes is scheduled for limited release later this year.
