What Is an Orgasm Physiologically?

A Note from James:

In the first episode with Dr. Nicole McNichols, we talked about chemistry, myths, and why communication matters more than performance. This episode goes deeper—into biology, anatomy, dopamine, desire, and the mechanics of pleasure.

There are a lot of myths around sex. Some are cultural. Some are Hollywood. Some come from bad science. And some just come from silence.

This conversation gets specific. We talk about orgasm, desire, scheduling sex, the so-called “missionary problem,” novelty in long-term relationships, and why so much of what we assume about men and women sexually just isn’t true.

If Part 1 was about mindset, Part 2 is about understanding how sex actually works.

Episode Description:

What actually happens in the body during orgasm? Why does anticipation sometimes feel better than the act itself? And why are so many of our beliefs about sex simply wrong?

In Part 2 of this three-part series, Dr. Nicole McNichols breaks down the biology of desire, the science of orgasm, and the myths that quietly sabotage long-term relationships.

She explains why dopamine peaks during anticipation, why consistency—not intensity—is often key to orgasm, and why “missionary” might be underrated. They explore the anatomy of the clitoris (including research only fully mapped in 2006), the orgasm gap, responsive vs. spontaneous desire, and why scheduling intimacy can actually increase desire.

This episode reframes sex not as performance, but as collaboration—an evolving, communicative process rooted in curiosity and growth.

What You’ll Learn:

• Why dopamine spikes during anticipation—and how to avoid the post-expectation letdown
• The difference between spontaneous and responsive desire (for both men and women)
• Why consistency is physiologically critical during orgasm
• The science behind the orgasm gap and what actually closes it
• Why scheduling intimacy can increase frequency and desire—not kill spontaneity
