What is the theme in Sexual Perversity in Chicago and the Duck Variations: Two Plays by David Mamet?

Sexual Perversity in Chicago is a play about four single people and their thoughts and experiences on sex. There are many sexual references throughout the play. However, there is less sex in the play than one might think. Rather, there is much talk about getting sex, various conquests and attempts. The only actual sex scene is between Bernard Litko and the unnamed woman in the hotel room. Even then, the act is not fully completed because the woman sets the hotel room on fire and Litko decides to get out while he can.
