Episode 382: Understanding Sexual Fluidity

Mar 25, 2025

Are you attracted to different types of people than you used to be? Has there been a shift in your go-to fantasy? Do you prefer different activities in the bedroom than you did before? Human sexuality is incredibly flexible. In today’s show, we’re going to dive into the subject of sexual fluidity in order to better understand how and why our sexual attractions might change over time.

My guest is Mark Cusack, a sexuality and relationship coach supporting people who may have complex, fluid or undefined sexual orientation or gender. Mark’s latest book is titled Fluid: A Guide for People with Flexible Sexuality.

Some of the specific topics we explore include:

  • What does it mean to be “sexually fluid?”
  • How often do fluid people experience shifts in their sexuality?
  • How is sexual fluidity different from bisexuality?
  • Why are some people more likely to experience sexual fluidity than others?
  • How is gender fluidity different from sexual fluidity?

You can check out Mark’s latest book here.
