Episode 497: Inside The World Of Breast Implants And Chest Surgery

More cosmetic surgeries are performed on the chest than almost anywhere else on the body, with breast implants leading the way. Not long ago, “bigger is better” defined the ideal, but we’re seeing a shift toward smaller, more natural results. So what’s driving that change? Today, we’re diving into the world of chest surgery, and what it reveals about beauty, power, and the making of the “ideal” breast. I am joined once again by Sarah Thornton, a sociologist, non-fiction writer, and author of four critically acclaimed books. Thornton’s most widely read book is Seven Days in the Art World, which is translated into over 20 languages. Her latest is titled, Tits Up: The Top Half of Women’s Liberation, which explores the significance of breasts across radically different social worlds. Some of the specific topics we explore include:
  • How common are breast implants today?
  • How have aesthetic goals shifted over time?
  • What shapes patient preferences in augmentation?
  • Are there cross-cultural differences in breast augmentation?
  • How do augmentation, reconstruction, and reduction differ in purpose and meaning?

Episode 496: How Breasts Became Erotic – The Surprising History

You might think that breasts are inherently sexual and that humans have always eroticized them. Historically, however, breasts haven’t always been seen this way, and even today, breasts are barely sexualized in some cultures. In today’s episode, we’re looking at the fascinating story behind how breasts became eroticized, and how the cultural meaning of breasts has changed over time. My guest is Sarah Thornton, a sociologist, non-fiction writer, and author of four critically acclaimed books. Thornton’s most widely read book is Seven Days in the Art World, which is translated into over 20 languages. Her latest is titled, Tits Up: The Top Half of Women’s Liberation, which explores the significance of breasts across radically different social worlds. Some of the specific topics we explore include:
  • How did decoupling breasts from feeding make them more erotic?
  • What role did infant formula play in that shift?
  • Historically, was breast sexualization partly a privilege of wealth?
  • How do culture and concealment shape what we eroticize?
  • Why is the nipple where we draw the line?

Episode 495: Why Even Happy Couples Fight (And How To Do It Right)

A lot of people believe that if you’re in the “right” relationship, you shouldn’t fight. They think that conflict means something is wrong or that you’re incompatible. However conflict isn’t a failure—it’s inevitable. In today’s episode, we’re rethinking what conflict really means and how to navigate it in healthier, more constructive ways. I am joined once again by Dr. Sara Nasserzadeh, an award-winning social psychologist, TED Speaker, and relationship expert. Her latest book, Love by Design: 6 Ingredients to Build a Lifetime of Love, introduces the Emergent Love Model, a framework born from research with hundreds of couples across 41 countries. Some of the specific topics we explore in this episode include:
  • Is it true that happy couples don't fight?
  • How can conflict avoidance be an even bigger problem than frequent conflict?
  • Why is it important to think about conflict as a disagreement rather than a fight?
  • How can couples navigate mismatches in their conflict style?
  • What does "healthy conflict" look like in practice?

Episode 493: Straight Men Who Have Sex With Other Men

We tend to think about sexual orientation as a fixed identity that's clear, stable, and easy to define. However, sexuality doesn’t fit into neat and tidy boxes like that. In this episode, we're diving into the world of heterosexual man who want to have sex with other men, and what this tells us about the complexity of human sexuality. I am joined once again by Kathy Kay, host of the Strictly Anonymous Podcast and author of the new book Strictly Anonymous Confessions: Secret Sex Lives of Total Strangers, a collection of real, unfiltered stories from people revealing their most private sexual thoughts and experiences. Some of the specific topics we explore include:
  • How common is it for heterosexual guys to have same-sex fantasies?
  • Are these fantasies and desires purely physical, or is there an emotional component as well?
  • Are these men just secretly gay?
  • Why is male same-sex behavior more stigmatized than female same-sex behavior?
  • Are women sometimes turned on by watching their husbands or boyfriends with other men?
