Intimacy, Breakups, and Dating in the Real World: A Conversation with Dr. Justin Garcia

Dating and relationships have never been simple — but in today’s world of apps, algorithms, and endless options, it’s easy to feel overwhelmed and disconnected. In this episode, I speak with Dr. Justin Garcia, Executive Director of the Kinsey Institute, evolutionary biologist, sex researcher, and author of the upcoming book The Intimate Animal. We talk about what our biology can (and can’t) tell us about love and desire, how technology is reshaping intimacy, and why breakups can hit so hard.

We also get personal — sharing stories about grief, recovery, non-monogamy, and navigating love in the real world. Dr. Garcia brings a refreshingly nuanced perspective, blending science, lived experience, and a deep respect for the complexities of modern relationships.

Key Takeaways

• Love and sex are biologically distinct but deeply intertwined. We’re wired for long-term bonding, but novelty and desire often create tension within those bonds.

• Breakups are more than emotional — they’re neurochemical. Love activates the brain’s reward systems, and heartbreak can mimic drug withdrawal.

• Modern dating can feel overwhelming because our brains haven’t evolved to handle endless digital choice. Intention and curiosity matter more than perfection.

• Non-monogamous relationships aren’t inherently less loving or stable. They often demand high levels of communication and negotiation.

• Infidelity is less about desire and more about secrecy. Even in non-monogamous relationships, broken trust hurts.

• There’s no perfect formula for love. Each connection is unique, and understanding yourself can help you show up better in relationships.
