Charlie Sheen found it "tough" trying to fulfil ex-girlfriend Bree Olsen's "insatiable" appetite for sex.
The 24-year-old porn actress - who lived with the actor and his other 'goddess' Natalie Kenly at his Los Angeles home - would be happy making love "19 times a day" whereas Charlie was content having sex a couple of times a day.
Bree - who broke up with the 45-year-old star in April - said: "Charlie was a two-a-day kind of guy. I'm insatiable when it comes to my sexual appetite - and I wasn't used to having to share.
"Charlie would try to keep up - but it was tough. I can just about get by on one-a-day - but would be happier having it 19 times a day."
Bree also admits one of the main reasons she left Charlie was because she found it hard sharing him with Natalie, because his second girlfriend would always be "fighting for attention".
In an interview with The Sun newspaper, the 24-year-old blonde beauty added:
"Sometimes he'd do it once with me and once with her. Sometimes he would want both of the times to be with me - and when Natty found out she'd get upset.
"She would spend the whole time fighting for attention and boast about things she had done like cleaning the dishes. She would get very upset and she would cry a lot.
"I was sleeping in the main bed with Charlie and for the first week or two she would get really upset. So I volunteered to sleep in the second bed for a bit to give them a chance."
