'I used to worry endlessly that I was some kind of freak, that my preoccupation with sex made me different from other women and isolated me from my friends. So I started a diary; I wanted to be able to freely express all my fantasies, concerns and actual experiences of sex. What I learned - to my surprise - was that I am no different to other women; I am just vocalising what so many others think about privately.' Abby is in her thirties, works in the arts and lives in London. This is her first book.
