Actor Joseph Fiennes finds filming sex scenes anything but arousing.

The 35-year-old star of Shakespeare In Love find it difficult to get turned on during raunchy scenes when surrounded by a whole film crew.

He explains, "With 20 hairy-a*sed sparks standing around, I never (get aroused). Take after take kills any desire.

"Like most actors I wonder whether it's really necessary for all the full-frontals and the t*ts-out stuff because most of it goes on the cutting-room floor in order to lower the certificate."
