How many people have you had sex with? In other words, what’s your “body count?” In this episode, we’re going to dive into the data. We’ll discuss the average number of sexual partners people report having, why men consistently report higher body counts than women, as well as why people seem to place so much emphasis on body count in the first place.

Episode 405: What We Get Wrong About Masturbation (Essential Listen)
There’s a surprising amount of anti-masturbation content on social media, much of it suggesting that masturbation is bad for your health. In today’s show, we’re going to delve into whether abstaining from masturbation actually boosts testosterone, whether you can really become “addicted” to masturbating, what science says about the purported health benefits of semen retention, and more.
In this episode, we’re revisiting a conversation with Dr. Eric Sprankle, which originally aired back in episode 275. Dr. Sprankle is an Associate Professor of Clinical Psychology and the co-director of the Sexuality Studies program at Minnesota State University, Mankato. He’s also a licensed clinical psychologist and AASECT-certified sex therapist, as well as author of the book, DIY: The Wonderfully Weird History and Science of Masturbation.
Some of the specific topics we explore include:
Why is the concept of semen retention increasingly popular?
Are there any health benefits to abstaining from ejaculation?
Is an orgasm obtained from self-pleasure really any different from an orgasm obtained through partnered sex?
Can women become “addicted” to their vibrators?
Is there an objective standard for what constitutes “too much” masturbation?
You can check out Eric’s website to learn more about his work.

Episode 404: Women Who Pay For Sex
Men are much more likely to report having paid for sex than women; however, there are probably more women paying for sex than we think. In today’s show, we’re going to do a deep dive into the world of women who pay for sex. We’ll be exploring what their experiences are like, why some women see paying for sex as being safer than having casual sex, and more.
My guest is Dr. Hilary Caldwell, a sex worker, author, academic, and sexologist. Her bold political memoir, Slutdom: Reclaiming Shame-Free Sexuality, challenges the enduring impact of slut shaming and argues for a world in which everyone can pursue pleasure without fear, stigma, or coercion.
Some of the specific topics we explore include:
Why is there less research on women who pay for sexual services relative to men?
How common is it for women to have paid for sex before?
Why do some women who patronize sex workers don’t consider themselves to have bought sex?
What are some of the main motivations for women to purchase sexual services?
What are women’s experiences with purchasing sex like? Do they tend to feel stigmatized?
You can check out Hilary’s website to learn more about her work.
