Episode 422: How To Break A Sexual Dry Spell
In long-term relationships, almost everyone will go through a sexual dry spell at some point. This is normal, and it doesn’t necessarily mean that there’s something fundamentally wrong with you or your relationship. However, the good news is that there’s a lot you can do to break the dry spell and get your intimate life back on track. Today, we’re going to explore the reasons why sex often disappears in relationships, and what you can do about it.
I am joined by Dr. Nazanin Moali, a licensed clinical psychologist, AASECT-certified sex therapist, and the host of the internationally acclaimed Sexology Podcast. Based in Los Angeles, she leads a successful private practice where she helps individuals and couples deepen emotional intimacy, overcome sexual challenges, and create more fulfilling relationships.
Some of the specific topics we explore include:
How many people are in sexless relationships?
What questions should we be asking when we find ourselves in a sexual dry spell?
How can you bring erotic tension back into your relationship?
What are ways to bring a sense of mystery and play back into sex?
How can we reinvent our date nights in a way that’s going to cultivate more erotic energy and excitement?
You can check out Nazanin’s website to learn more about her work.

Episode 421: Digital Intimacy and the Rise of Erotic Camsites
As many as 1 in 5 adults have visited an erotic camsite. However, the appeal of these sites goes far beyond sexual gratification. A new study of camsite users finds that they are often looking for emotional connection and fulfillment, too. But are they actually finding it? In today’s show, we’re diving into the data and exploring whether intimacy is really an experience that can be commodified.
I’m joined once again by Ellen Kaufman, a Senior Research Associate at the Kinsey Institute. Her research focuses on the intersection of sexuality and technology, exploring how our relationships and overall sexual and emotional wellbeing are shaped by new modalities of connection.
Some of the specific topics we explore include:
How is a camsite different from a traditional porn site?
Who are the primary visitors of camsites?
To what extent do users feel emotional bonds with cam models?
Can we develop authentic intimacy in a transactional setting?
You can check out the website for the VIBES research team to learn more about Ellen’s work.

Episode 417: The Connection Between ADHD And Kink

She specializes in the intersection of ADHD, relationships, and sexuality. Leann runs the podcast ADHD Realities and is currently writing a book on ADHD and low sexual desire.

In what ways can kink enhance sex for persons with ADHD?
How can BDSM help people who might have sensory sensitivities?
In what ways can scene negotiation help people with ADHD in terms of attention management?
Why is there a link between neurodivergence and kinky interests more broadly?
