Courteney Cox has revealed one of the problems in her marriage to David Arquette was that he constantly wanted sex.

The actress insists her estranged husband has a strong libido and his irrepressible sex drive was a factor in their decision last October to have a trial separation after 11 years of marriage.

Referring to David's recent confession that he hit on her during a trip to Disney World with their six-year-old daughter Coco, she said: "It was early in the morning. This is one of our problems in our relationship. Whenever I would need consoling from David, he could not literally put his arm around me for one second without completely getting a boner ... So [Disney World] just wasn't the right time and I don't want to confuse the issue. We're going through a hard time."

Courteney made the confession during a joint interview with David on Howard Stern's Sirius XM radio show, and during the chat the 39-year-old seemed to suggest his 46-year-old wife was through with the marriage.

Speaking to the former 'Friends' star, he said: "I think you're over it, baby. You just need to admit it and we just need to figure out next Steps."

To which she replied: "Wow, that's heavy. You can't count [Disney World] as the place where you know I'm not into you. I had just woken up. I don't think [sexual attraction] is the issue. The truth of the matter is that we love each other so much. We have such affection for each other but we are very different ... I'm a homebody. David doesn't drink anymore, he's completely sober, but he likes to go out and dance. I don't want to inhibit him in his life. He really is a very gregarious guy, he's very outgoing. I'm much more of an introvert."

Courteney - who appears in new horror movie 'Scream 4' with David, who completed a stint in rehab for alcoholism - also insisted she hadn't dated anyone since agreeing to the split, despite being romantically linked to her 'Cougar Town' co-star Josh Hopkins - who she recently went on vacation with to the Caribbean.

When asked if she'd had sex since the break-up, she bluntly said: "I have not had sex."
