Episode 457: Gay Men Who Have Sex With Women Dec 12, 2025

Show notes

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?

You can visit Joe’s website to learn more about his work.

My guest is 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.

Episode 455: The New Rules Of Cheating Dec 05, 2025

Show notes

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?

Show notes

It’s November again, and that means a bunch of people on the internet are giving up masturbation for the month.

He’s also a licensed clinical psychologist and AASECT-certified sex therapist affiliated with the Minnesota Sexual Health Institute. His latest book is DIY: The Wonderfully Weird History and Science of Masturbation.

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

Where does the idea of masturbation as sinful originate?
Historically, how have religious and political figures dissuaded people from masturbating?
When did masturbation start to become a public health concern?
How has the rise of social media coincided with the rise of negative views of masturbation?

You can visit Eric’s website to learn more about his work.
