In this episode, Dr. Brandon discusses why men tend to have a higher sex drive than women in long-term relationships—and how biology, emotional patterns, and relationship dynamics all play a role.

00:41 Research and Misconceptions
Dr. Brandon breaks down how common beliefs about equal sex drives aren't backed by actual research.

01:56 Impact of Relationship Duration
She explains how women’s sex drive often drops in long-term relationships, even if it was high early on.

04:36 Dual Control Model of Sexual Desire
The model shows how desire depends on a balance between what turns someone on and what shuts them down.

05:49 Inhibitory and Excitatory Factors
Women tend to have more things that reduce desire and fewer that boost it—especially over time.

11:37 Understanding and Improving Intimacy
Dr. Brandon emphasizes that couples aren’t stuck—understanding these dynamics can help rebuild connection.
