If there's one drama that caught our attention and triggered binge-watching this year, it's the Golden Globe-winning new series The Affair, starring Dominic West and Ruth Wilson.

The pair play a diner waitress and a teacher who embark on an extramarital relationship one summer. Naturally sex is big part of the narrative and the British acting heavyweights say they didn't approach it lightly.

“Dominic and I would really ask ourselves what was necessary from all the sex scenes," said Wilson, 33, in a new interview with Vogue. “Neither of us wanted to do things that were gratuitous.”

West, 45, added that they wanted to steer clear of the explicit nudity which frequently occupies popular shows such as Game of Thrones. "Recently there are so many shows where actresses are required to get naked. And it's just tits and sex everywhere. We didn't want it to be like that and we fought hard to make sure everything we did counted for something.”

“It's not easy for me to get my kit off,” said Wilson on the topic of going naked in front of the camera. “I am self-conscious about my body just like any other woman would be with a camera on it. On top of which, the producers didn't provide trainers for us during the five months of shooting so it was up to me to keep in shape.”

Wilson also insisted that both actors share simulated-sex duties: “We used to say that if we were doing sex scenes we needed to do equal orgasm faces.”
