I was still young when I missed Beijing. I was favourite to win a medal but I knew I had time. My coach advised me to stay at school and finish my exams. Even if I had gone and won the Olympics, I might not have handled the pressure. So I moved on.

When I am training, I don't want any disturbances. I have to be focused, not losing sight of my targets. I cannot evade the fact that I am now well known and I have made already some money, but you can learn how to deal with it.

We exist in this weirdly schizo culture, where sex is everywhere in the media, and yet, at the same time, you don't sit down and have a conversation about what you did in bed last night with your friends. Despite the ubiquity of sex, it's still a taboo when it comes to day-to-day conversation.
