Episode 510: The Science Of Sexual Arousal

from Sex and Psychology Podcast · host Dr. Justin Lehmiller

A lot of people think that if you’re attracted to someone, arousal should just naturally happen. But it’s not that simple. In this episode, we explore the science of sexual arousal, the many pathways through which desire can emerge, and how stress, trauma, burnout, and major life experiences can reshape our relationship with pleasure. My guest is Kayna Cassard, a sex therapist, painful sex specialist, certified trauma therapist, and author of the book Arousal, Answered: An Expert’s Guide to Authentic Pleasure and Liberating Sex. Her mission is to help others liberate themselves from outdated sexual scripts and empower them to rewrite their authentic sexual narratives. Some of the specific topics we explore in this episode include: How can understanding the brain unlock more pleasure? Why is desire more complex than spontaneous vs. responsive? What role do stress, safety, and connection play in arousal? Why is it so hard to stay present during sex? How can becoming more embodied enhance desire? You can visit Kayna’s website to learn more about her work. Got a sex question? Send me a podcast voicemail to have it answered on a future episode at speakpipe.com/sexandpsychology. *** Thank you to our sponsors!  If you’re ready to ditch the shady stuff and choose a libido supplement that’s effective and that you can feel confident about, it’s time to check out Drive Boost.
