What metaphors are used in The Blue Room by David Hare?

The Blue room is a motif and a metaphor for sex. The most obvious motif in The Blue Room is sex, in all its many guises. In the play, sex is shared between a prostitute and a john, a student and an older, married woman, a politician and his wife, an artist and a model, an actress and a writer, and so on and on. In every instance, however, the build-up prior to the sexual act is more energetic and exciting than the act itself which, accordingly, is never shown on the stage. The characters all long for satisfying experiences, and some seem to be seeking meaningful relationships, but their constant changing of partners in a sexual roundelay thwarts their chances of ever finding meaning and substance with other human beings.
