In this episode of A Broad Sex Education, we’re heading back to health class to uncover what school skipped about penis anatomy. From the corpora cavernosa to the urethral sponge, we break down the internal and external structures, bust myths about erections, and demystify foreskin and circumcision.

Then, in our math lesson, we explore the data behind penis size statistics, the truth about “average,” and how self-reporting has distorted expectations. We also highlight erectile dysfunction research and why penis size isn’t actually a performance metric.

📌 Part 2 of “The Hard Facts of the Penis” drops in two weeks, where we’ll head to anthropology class to explore how language, culture, and shame shape the penis’s story—and wrap up with a science pop quiz to test your knowledge on sperm speed, survival, and some seriously surprising stats

We’re on summer break and taking you with us — straight to Amsterdam. Here’s a quick check‑in and a sneak peek at what’s coming next on A Broad Sex Education.

In this episode of A Broad Sex Education, we’re breaking down what school left out about orgasms and sexual response. We trace the history of orgasmic lore, from Victorian-era hysteria myths to the groundbreaking research from Masters & Johnson. Then we shift to social science, unpacking sexual response models—from Masters & Johnson’s four phases to the Dual Control “gas and brakes” framework—to understand how desire, arousal, and pleasure actually work. Finally, we crunch the numbers with a math-themed pop quiz on orgasm statistics, the satisfaction gap, and who’s really finishing.

🎬 Study Break: Materialists (2025)

Brooklyn and Cin took a field trip to see Materialists and they’ve returned to study hall with opinions. Asa hasn’t seen it yet, but that’s not stopping us from breaking down what this film has to say (intentionally or not) about dating and relationships.

Join us for a laughter-filled Study Break between lessons, brought to you by A Broad Sex Education. ⚠️ Spoilers ahead!

How many times have you heard someone use the word “sex” when they meant “gender”? Or treated gender and sexuality like they’re the same thing? In this foundational lesson, we’re breaking it all down.

In this episode, we unpack the differences between sex, gender, and sexuality and explore why those lines often get blurred. From chromosomes to cultural norms, we look at how biology, identity, and attraction each play a role in how we understand ourselves and others.

Class subjects include:

• Social Science: understanding the distinctions between sex, gender, and sexuality, plus a look at early models used to define human attraction
• English: a vocabulary lesson on the wide spectrum of sexualities and evolving identity terms
• Pop Quiz: History: a rapid-fire look at queer history and the people who helped redefine how we see identity

Whether you’re untangling outdated beliefs or just starting your journey, this episode gives you the language, tools, and clarity you wish you had in school.

In this episode, we’re diving deep into why sex has long been considered a taboo topic in America. We'll explore the historical roots of sexual repression, from ancient confessions to postal obscenity laws, and how different cultures around the world approach sex education and sexuality. We'll also break down the numbers — are societies that embrace open conversations about sex actually safer and happier?

Get ready for a history, geography, and math lesson as we uncover how stigma took hold and what it means for us today.
