What determines sexual orientation—biology, psychology, or something else entirely? In this powerful and revealing episode, we explore the science of sexual identity, from early theories of sin and morality to today’s cutting-edge research on hormones, genetics, and brain development. Discover how the concept of being "born this way" took shape, what researchers found about prenatal testosterone, and why the controversial "gay gene" sparked both hope and backlash.

We dive deep into the lives of bisexual individuals and challenge the myth of sexual binaries. You'll learn how cultural bias, psychiatric theories, and evolutionary biology shaped the way society views same-sex attraction. Plus, explore vibrant sexual subcultures that offer new models for love, desire, and identity—including gay bathhouses, lesbian polyamory, and the Radical Faeries.
