Episode 438: Should You Share Your Sexual Fantasies?
October 7, 2025 by Justin Lehmiller

What happens when people decide to share their sexual fantasies? How does it usually go? In today’s show, we’re going to explore how many people have ever shared their fantasies with a partner before, the five most common reasons that people decide to open up about them, as well as how partners usually react to fantasy disclosure.
I am joined by Matthew Kimberley, a lecturer in Psychology at Birmingham City University. He researches sexual fantasies and also leads the Gender, Sexuality and Intimate Relationships Research Lab.
Some of the specific topics we explore include:
- Is it common for people to share their fantasies with their partners?
- What is the most common reason for sharing a sexual fantasy?
- Why do some people choose to keep their fantasies secret?
- Do partners typically respond positively or negatively when fantasies are shared?
- When is sharing your fantasies a good idea?
You can check out the Gender, Sexuality and Intimate Relationships Research Lab’s website to learn more about Matthew’s work.
