Libido, Loneliness & the Science of Lasting Intimacy
In recent years, we’ve been hearing something surprising — millennials and Gen Z are reportedly having less sex than any generation before them. In Japan, more than 40% of young adults say they’ve never had sex and, in many cases, aren’t even interested.
Relationship expert Esther Perel calls it a “sexual recession” — but she says it’s about more than just libido. It’s about loneliness, disconnection, and a loss of what she calls “clean time” — moments of undivided attention and presence. You can’t get oxytocin, the bonding hormone, in pill form. It comes from being seen, heard, and truly present with one another.
I connect this bigger cultural shift to the biological realities I’ve been exploring over the past few episodes. In Episode 19, I share Dr. Sabrina Salt’s insights on the three biggest drivers of sexual health: hormonal balance, blood flow, and nerve conduction. We discuss why testosterone — in both men and women — is critical for libido, how estrogen affects more than we realize, and why diet, especially a carnivore approach, can dramatically shift sexual wellbeing.
From oysters as a “superfood of desire” to the cautionary debates around iodine supplementation, this episode dives into both the science and the nuance of hormonal health. I even share perspectives from Dr. Alan Christensen that challenge the iodine advocacy of experts like Dr. Bright and Dr. Brownstein — and why testing, awareness, and self-education are essential before supplementing.
But this conversation isn’t just about biology. I return, as promised, to the role of relationships. The Gottmans’ decades of research show how simple gestures — like a goodbye kiss or a six-second embrace — have profound impacts on health and connection. As John Gottman puts it, “Every positive thing you do in a relationship is foreplay.”
The takeaway? Desire isn’t just about hormones. It’s about presence. About emotional safety. About knowing each other’s histories — including the wounds — and choosing to initiate connection instead of waiting for it to appear.
