Episode 457: Gay Men Who Have Sex With Women

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.

Episode 455: The New Rules Of Cheating

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.
