Episode 512: Why Chastity Turns People On

Historically, chastity was associated with suppressing sexual desire. Today, however, it often means something very different. For many people, it's a way of exploring desire, anticipation, control, intimacy, and pleasure. In this episode, we're diving into the psychology of chastity, including why people are drawn to it, who's into it, and what it can teach us about human sexuality more broadly. My guest is Paul Botto, the COO of KINK3D. He’s been working in the queer and kink community in San Francisco for the past 10 years, joining KINK3D in 2021 as the company’s first hire. Some of the specific topics we explore in this episode include:
  • What does chastity mean in modern sexual culture?
  • How has the meaning of chastity changed over time?
  • What do people find psychologically appealing about chastity?
  • Why can limiting pleasure intensify desire?
  • Why are some people drawn to chastity outside of kink?

Episode 511: The Five Dimensions Of Sexual Desire

Why do some people need emotional connection to feel desire, while others are more responsive to novelty, touch, or fantasy? And why can the exact same sexual experience feel exciting one day and flat the next? In this episode, we explore the five dimensions of desire and how understanding your arousal architecture can transform your sex life.

I am joined once again by 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 Her mission is to help others liberate themselves from outdated sexual scripts and empower them to rewrite their authentic sexual narratives.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:
  • What is the Arousal Architecture, and what does it reveal about desire?
  • How do the five dimensions of arousal shape sexual desire?
  • How can arousal needs shift across relationships and situations?
  • How can understanding your arousal architecture improve your sex life?
  • How do we separate what genuinely turns us on from what we think should turn us on?

Episode 510: The Science Of Sexual Arousal

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?

Episode 509: Out-Of-Control Sexual Behavior In Women

When people hear about "out-of-control" sexual behavior, they tend to think of men. But women can struggle with it too, and their experiences have often been overlooked or misunderstood because most of the research and treatment models were built around male experiences. Today, we’re exploring the psychology of out-of-control sexual behavior in women, and what people often get wrong about it.

I am joined once again by Jess Levith, a licensed marriage and family therapist and AASECT certified sex therapist. She’s fully trained in both attachment-focused EMDR therapy and trauma-focused acceptance and commitment therapy, works with LGBTQQIA+ and kinky folks, consensual non-monogamy, women’s sexual health, and out-of-control sexual behavior. Some of the specific topics we explore in this episode include:
  • What do we misunderstand about women's experiences with problematic sexual behavior?
  • How do you distinguish between a high sex drive and sexual behavior that truly feels out of control?
  • How do clinicians separate genuine sexual dysregulation from sexual shame?
  • How does out-of-control sexual behavior differ in women and men?
  • If someone feels their sexual behavior is out of control, where should they start in seeking help?
You can follow Jess on Instagram to stay updated 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!

Episode 508: When Your Sexuality Changes Later In Life

Most people think sexuality is something we figure out early in life. But for many people, major realizations about their sexuality don’t happen until much later, sometimes after decades in heterosexual relationships or marriages. Today, we’re exploring the psychology of coming out later in life and what happens when you discover aspects of your sexuality you never fully understood before. My guest is Jess Levith, a licensed marriage and family therapist and AASECT certified sex therapist. She’s fully trained in both attachment-focused EMDR therapy and trauma-focused acceptance and commitment therapy, works with LGBTQ+ and kinky folks, consensual non-monogamy, women’s sexual health, and out-of-control sexual behavior. Some of the specific topics we explore in this episode include:
  • Why might someone not fully understand their sexuality until later in adulthood?
  • Is coming out later in life always about repression, or can something else be happening?
  • What is sexual emergence, and how does it differ from coming out?
  • How can people approach conversations about changing sexuality with long-term partners in honest, compassionate ways?
