The Twilight actor said that he struggled with some aspects of his sex scenes in the upcoming romantic drama.
Showbiz Spy quotes him as saying: "When you end up doing it, you have this little patch on your privates. I didn't really tape it up properly, so I'd spent so long taping it round myself and then literally it falls off within one second and it's taped to the sheet.
"And you realise the whole crew are looking directly at your butt crack. I can’t think of anything exciting for them about this. It gives you a lot of respect for porn stars."
