The 38-year-old says she politely urges filmmakers to avoid sex scenes as she feels they are of no use in a movie's plot, reports dailystar.co.uk.
"Love scenes are always awkward. They're awful. I've managed to really skip through them. When I read that my character has a love scene, I carefully address it with the director: 'Can we please cut this out? It's gratuitous and there's no need for it,' and thankfully that has happened," Mendes said.
"I try to avoid them whenever I can. I have done a couple of things that have been appropriate for the films I've been in, but I've never done a simulated sex scene because I feel like they're rarely appropriate," she added.
