The Affair star Dominic West has filmed so many sex scenes he "knows the Kama Sutra backwards".
Dominic, 46, plays teacher Noah Solloway, who cheats on his wife with a waitress (Ruth Wilson), causing his life to fall apart.
The award-winning show is famed for its frequent steamy scenes and the actor told GQ Style he had "gotten very good at all the technical names".
"It's so ludicrous now. We shout for suggestions from members of the crew. I remember last season we shouted out, 'We've done it up against the wall, we've done it against every piece of furniture, we've done it upside down ... ' and someone shouted out, 'Reverse cowgirl?' I mean what the f*** is that?"
"I know the Kama Sutra backwards," he added.
The actor has also appeared nude on screen in Jodie Foster-directed Money Monster, which starred George Clooney and Julia Roberts.
Last month it was announced Eton-educated Dominic would be appearing in The Square alongside Mad Men's Elisabeth Moss.
The first two series of The Affair were shown on Sky Atlantic. Season three airs in the US in November.
