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".
