The actor opened up about his insecurities over his physical appearance while talking to Irish Independent, reports dailymail.co.uk.
"I think I am like anyone, I have massive hang-ups about my physical appearance. I was always fighting against stuff when I was a kid. I always felt skinny and small. Now, I'm 32... I have the same insecurities when I was a kid and when I see an image of myself, all I see is this skinny kid and I don't like it," he said.
The 32-year-old, who has shot numerous nude scenes for the erotica drama, also said that he didn't believe the appreciation that came his way while filming for the movie.
"No matter how many times you get filmed with your top off and the photographers are saying 'Oh, you look great, add more oil", and all that, you have all these things ingrained in your head -- insecurities about yourself.
"All the people in the world saying stuff like this isn't going to alter that. I only had four weeks to work out for this role. I would have liked more time. But like I said, I don't think I am ever going to be happy with how I look," he added.
