Episode 460: Why People Have More Sex Around the Holidays

If you're feeling hornier than usual right now, it's not just you! The winter holidays are a time of year when sexual interest and behavior reliably increase. We see this in everything from a spike in condom sales to an increase in sexual injuries to a peak in STD rates early in the new year. So why is that? That's what we're going to explore in today's episode. Some of the specific topics we're discussing include:
  • How (and why) does sexual behavior change with the seasons?
  • Why is Santa such a popular sex symbol at this time of year?
  • How do you prevent holiday stress from spoiling the mood?

Episode 459: What 136,000 Erections Reveal About Men

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.

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?

Episode 458: How Erections Really Work (And Why They Fail)

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. My guest is 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 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?
