The 26-year-old actor, who plays heartthrob vampire Edward Cullen in the 'Twilight Saga' franchise, has admitted that he improvised for the intimate on-screen love scenes with co-star and real life girlfriend Kristen Stewart in both 'Breaking Dawn' films but was so impressed with his moves that he thinks he should be in charge.
Robert explained: "I haven't even seen the scene and I feel like I did half of it by myself. The only thing I really remember is doing the thing on her clothes [pulling down her zipper] which was my idea, of course it was my idea.
"If you notice the little thing ... we kind of end up at the top [of the bed] and that was my idea as well because we made a little rig for it and that was my idea.
"I should be a director, just for sex scenes. Other than that I just remember staring into the camera and trying to make sexy faces and I don't think it got in the movie."
He also revealed that both sex scenes between Edward and Bella Swan (Kristen) from the two films were shot in the same week and he found the transition from one to the other a struggle.
He joked to Hollywood Life: "The weird thing ... we were shooting [Breaking Dawn - Part Two] sex scene and this [Breaking Dawn - Part One] one in the same week and so we did the last one first and the second one was supposed to be dramatically different and so much better.
"But the first one was really great and you're thinking 'uh, well there's only so much the human body is capable of!' Especially looking at it externally. I'm not like a ballerina or something."
