19-12-2025 | 27 Min.
Erectile dysfunction has long been treated with guesswork and one-size-fits-all solutions. But new technology is changing that by making erections measurable. In this episode, we explore the FirmTech TechRing, a wearable that tracks erection data during sleep and sex, and what insights from over 136,000 erections reveal about erectile fitness, overall health, and the future of data-driven sexual medicine. I am joined once again by Dr. Elliot Justin, the CEO and founder of FirmTech, a sextech company focused on keeping men fit and firm for a lifetime of lovemaking. He is an Emergency Medicine specialist and health care technology consultant who has spent 25 years practicing emergency medicine and directing ERs. Some of the specific topics we explore in this episode include: How is the TechRing different from a traditional penis ring? What can real-time erection data tell men about their health? How does using an erection ring compare to taking an ED medication? How can an erection ring make sex better?

16-12-2025 | 25 Min.
What actually has to happen inside the body for an erection to occur? And what is the most common cause of erectile dysfunction (ED)? In today’s show, we’re diving into the science of how erections work, as well as why men sometimes struggle to get or maintain them. We’ll also unpack some common misconceptions about ED and discuss why the standard “just take a pill approach” overlooks a bigger issue.

He is an Emergency Medicine specialist and healthcare technology consultant who has spent 25 years practicing emergency medicine and directing ERs. Some of the specific topics we explore in this episode include: What are the biggest things people get wrong about erectile dysfunction? What is venous leak, and why is it such an under-diagnosed contributor to ED? Why do nighttime erections happen, and what do they tell us about men’s health? What’s the problem with using pills as a one-size-fits-all solution to ED? Check out FirmTech’s website to learn more and use code JUSTIN15 to save 15% off your purchase. Got a sex question?

Episode 457: Gay Men Who Have Sex With Women
12-12-2025 | 29 Min.
Most people think men’s sexual orientation is pretty straightforward: if you’re gay, you only sleep with men, and if you’re straight, you only sleep with women. But things aren’t always that simple. In today’s show, we’re exploring a reality that doesn’t fit the script—gay men who are out and confident in their identity, but who sometimes sleep with women. I am joined once again by Dr. Joe Kort, the clinical director and founder of The Center for Relationship and Sexual Health in Royal Oak, Michigan. He is a board-certified clinical sexologist and author of multiple books, including Cracking the Erotic Code: Helping Gay Men Understand Their Fantasies. Some of the specific topics we explore in this episode include: What are the main reasons why some gay men have sex with women? Why might a woman want to have sex with a gay man? Does your sexual behavior necessarily have to align with your sexual identity? Why do people sometimes engage in behaviors that don’t seem to match up with their sexual orientation?

Episode 455: The New Rules Of Cheating
05-12-2025 | 32 Min.
People’s definitions of cheating are evolving. Infidelity isn’t just about physical betrayal anymore. It’s emotional, it’s digital, and sometimes it doesn’t even involve another human at all. In today’s show, we’re diving into the new rules of cheating. We’re also going to talk about how modern technology is making it harder than ever to keep infidelity a secret. I am joined once again by Dr. Amanda Gesselman a research scientist and head of the VIBES research team at the Kinsey Institute at Indiana University. Digital intimacy is a major focus of her research, including how people use tools like camsites, AI companions, dating apps, and social media to navigate connection and desire. Some of the specific topics we explore in this episode include: What do people today think “counts” as cheating? Is watching porn a form of infidelity? What about sexting with an AI chatbot? How many people suspect a partner has cheated on them before? What kind of detective work do people do to determine if a partner has cheated? How do we balance the benefits and challenges of digital intimacy? To learn more, you can read a brief report of this study here. Got a sex question?
