I proposed to my previous girlfriend [American ballerina Tiekka Schofield] on top of the Eiffel Tower. But for various reasons the relationship broke down after four years. I had this real sense of failure. I had spent four years of my life trying to make it work! I didn't even want to think about having another relationship. My response was to have a lot of one-night stands. I'm comfortable with the idea that a man and a woman can just have sex and nothing else. Like many men, I find it easy to compartmentalise.
