This episode explores the idea that sexual categories have socially-defined meanings that evolve over time. Individuals develop their sexual self through telling their story to position themselves within these social definitions.
How we talk about sex shapes how sex is talked about. If that sounds like a circular argument, good, because I see our social understanding of sex as a feedback loop. The words we use, the meanings we ascribe to them, and the context in which they are given, all contribute to the way we and others understand the topics we describe. Words can be arbitrary, but they are no less important in communication.
