Source: Bang Showbiz NewsJack Nicholson no longer has the energy to be a "womaniser". The 75-year-old actor doesn't play down the fact he's bedded countless women in his life but he feels "uncomfortable" at being branded a "sex legend".Jack - who has had high-profile relationships with actress Anjelica Huston, who he was with for 17 years, singer Michelle Phillips and model Janice Dickinson - said: "I am an extreme person. If someone says, 'Jack, you are a womaniser,' I don't deny it. But the life of a gigolo always ends badly."That is one of the reasons I feel uncomfortable about all that 'sex legend' stuff."I no longer have the energy to both work and fool around. So the last few movies I've done, I have hardly left the hotel at nights. It was completely different when we were making 'The Shining'."I was living in London, which is one of my favourite cities on Earth. The 17-week filming schedule at Pinewood Studios ended up as 47 weeks because the director, Stanley Kubrick, did so many takes for every single scene."I thought to myself, 'OK, I'm going to show all of these people. I am working with the toughest director in the business - and I am going to burn London to the ground every night with partying.' "Jack also "regrets" being so angry throughout his life and admits he should have learned "long ago" how to calm down in situations. The iconic Hollywood star believes he would have been happier if he'd learn to control his rage. He added in an interview with The Sun newspaper: "Anger has always been a problem and every once in a while I just have to let it out. I always regret it later. After a couple of hours I calm down and think, 'What way could I have solved that problem other than blowing up?'"I should have learned how to do that long ago and that would have made my life easier - with less apologising."
