Ashton Kutcher refuses to watch his wife Demi Moore's sex scenes on screen, because he suffers a jealous rage seeing her with other men.

The actress has jumped into bed with countless Hollywood stars, all in the name of art - including Woody Harrelson in Indecent Proposal, Rob Lowe in About Last Night and Michael Douglas in Disclosure.

But Kutcher switches off when her sees her with another man.

He explains, "In real life, I'm not jealous. But I can't cope with watching her with another guy on film. As an actor, I know that any feelings you're showing are manufactured. But I still don't want to fool my mind into thinking she's into another guy."
