The quote presents a contrasting comparison between two lovers, David and Stephen, highlighting the differences in their sexual experiences. With Stephen, the encounters are characterized by emotional depth, creativity, and unpredictability, which keeps the narrator engaged despite the uncertainty of the experience. This suggests a more artistic, imaginative approach to intimacy, where exploration plays a key role.

In contrast, David represents a more mechanical and straightforward approach to sex. The narrator likens the experience to operating a lift—efficient but lacking in romance. This emphasizes a functional and predictable nature of intimacy with David, where pleasure is achieved through a systematic, almost clinical process. The differing sexual experiences reflect deeper emotional connections and highlight contrasting aspects of relationships.
