The Penguin Book of Infidelities by Stephen Brook
There is one aspect of life that has not yet received the accolade of anthology: extra marital sex, illicit sex, sex for hire. The attraction of this theme is that the literary material, whether fictional or poetic or in the form of memories, is so rich. Covering such subjects as prostitution, mistresses and courtesans and gay love, this book includes sources such as Jean Rhys, Colette, Flaubert and Frank Harris.
