Watching the movie I got the feeling he's probably body conscious or slightly insecure just from his body language throughout the film. His hands were always covering his stomach when they were shirtless and he was wearing a buttoned up shirt in the same scene that Taylor was fully nude in - which he probably requested. Hopefully he feels more confident in his next projectMatthew confirmed he did the sex scene/hands but yeah I also heard the close up body shot while they were standing was not him
