David: (after being honoured at the BBC Sports Personality of the Year awards for swimming the English Channel for charity) The worst part was the cold, it really gets you down so I had to start thinking about Abba songs to keep me happy, and I thought about you a lot. I saw a lot of jellyfish, but luckily I didn't get stung. I did go through some sewage.
David: Oh yes, of course I was bullied - The boys used to call me Daphne, which was meant to put me down. I was very camp.
David: I don't have a lot to share with other men. My heart sinks when I get into a taxi and someone starts talking to me about football.
David: I was the kind of person who got bullied and loved the attention of it.
David: I love wearing drag.
David: I don't get recognized much, and am very happy with that. The fans I have met have all been delightful.
David: There's a little bit part of me that thinks maybe I should go back to putting on a dress and making people laugh.
