"Sexual liberation" is the title of this chapter's dialogue. It's a reference to the idea of sexual freedom, which is the idea that a man and a woman should be able to enjoy each other's company without worrying about what other men think of them. In other words, a woman and a man shouldn't have to share the same bed, the same room, or the same bathroom. This chapter is all about sexual liberation, and it's all about the two of them being able to do whatever they want with each other.
