The comedian admits at the height of his womanising he would often bed multiple girls in the same day and achieved the incredible number of conquests during a trip to Ireland.
Speaking about his prior sex addiction, he told Big Issue magazine: ' was having sex with different women three, four, five times a day. It was bacchanalian . in Ireland, nine in one evening.'
The 'Arthur' star's former lovers include supermodel Kate Moss, Australian actress Teresa Palmer and allegedly Playboy mogul Hugh Hefner's ex-girlfriend Holly Madison.
Although he has bedded countless girls, Russell ' who is now married to pop star Katy Perry ' insists not every encounter was earth-shattering.
The 35-year-old comic actor also admits he used his fame to skip the pleasantries of dating and go straight to the sex.
He said: 'When you have sex that often, by a law of averages you're likely to have boring sex. But also, you do encounter a lot of intrigue, you learn about people's behaviour very quickly ' the smells of people, the way they carry and present themselves. The fame and kind of will that I had meant that, instead of taking someone for a date and then going to the pictures and then calling them, I was able to go, 'Let's do sex right now!' '
