When I think about sex it makes me realise how alone I feel.

I like poor materials. I couldn't see myself making a bronze sculpture - it's not me. I like neon, because it's moving constantly and like drawing. The chemicals going through the neon turns me on really - it's sexy. I like fabrics, but one of the main things with objects is that I really have to love them before I can use them. I have to have the object around me a long time. The little chairs I used in my last White Cube show are ones that my dad bought for me. A sort of a psychometry with objects and things. It's like the pieces I've made are my things.

One thing that success has taught me is censorship.

They grew really quickly. One minute I didn't have any tits and the next I had the biggest tits in the world.

It pleases me that people can be interactive

There are things going on in galleries recently that have shocked me. What I'm going to say is really controversial, but what I find the most provocative is the commerciality of art in general. And the fact that a lot of people have forgotten what the meaning of art is and what the intention behind it is.

When it comes to words I have a uniqueness that I find almost impossible in art – and it's my words that actually make my art quite unique.
