Sex and Psychology Podcast

Humans have always looked for ways to enhance sex, but some of the most popular tools weren’t even meant for that purpose at all. One drug, originally developed for heart conditions, made its way into nightlife and became closely tied to sex. In today’s episode, we’re talking all about poppers, including how they work, how they became linked to pleasure, and why they’re still so controversial.

I am joined once again by Adam Zmith, a writer and multi-format producer. His books include Deep Sniff: A History of Poppers and Queer Futures, as well as Solemates: A History of Our Fetish for Feet.

Some of the specific topics we explore include:

What exactly are poppers?

Why do people use them to enhance sex?

How did they become embedded in queer nightlife?

What myths have fueled stigma around them?

Are there any risks in using them?

My guest is Adam Zmith is a writer and multi-format producer. His books include Deep Sniff: A History of Poppers and Queer Futures, as well as Solemates: A History of Our Fetish for Feet.

Some of the specific topics we explore in this episode include:

Dating apps make it seem like you can swipe your way to the perfect partner. But attraction isn’t something we can fully predict from profiles. It emerges through interaction. So what happens when we try to optimize something that’s inherently unpredictable? In this episode, we break down the psychology of online dating and how to approach it more effectively.

I am joined once again by Dr. Paul Eastwick, a Professor of Psychology at UC Davis, where he serves as the head of the Social-Personality Psychology program. He hosts the popular podcast Love Factually with his long-time colleague, Eli Finkel, where they analyze rom-coms and romantic dramas from the perspective of relationship science. Paul is also author of the new book Bonded by Evolution.

Some of the specific topics we explore in this episode include:

Why might using multiple dating strategies improve your odds?

Can AI predict attraction better than we can ourselves?

How accurate are first impressions on dating apps?

Is there an optimal timeline for meeting in person after matching?

What strategies lead to healthier online dating experiences?

You can check out Paul’s website to learn more about his work.

Most of us think we know what we’re looking for in a partner. We have a “type,” a mental checklist, and the belief that if someone checks enough boxes, everything else will fall into place. But decades of research suggest that attraction and compatibility don’t work that way. In this episode, we’ll unpack how attraction really unfolds and why chemistry is so hard to predict.

My guest is Dr. Paul Eastwick, a Professor of Psychology at UC Davis, where he serves as the head of the Social-Personality Psychology program. He hosts the popular podcast Love Factually with his long-time colleague, Eli Finkel, where they analyze rom-coms and romantic dramas from the perspective of relationship science. Paul is also author of the new book Bonded by Evolution.

Some of the specific topics we explore in this episode include:

What’s the link between what we say we want and who we actually fall for?

Do we really have a “type” when it comes to romantic partners?

Why is it so hard to predict whether two people will feel a spark?

How can we improve our chances of finding a compatible partner?

How much does long-term satisfaction depend on initial compatibility?
