Why Men Lose Interest in Sex: Habituation, the Coolidge Effect, and Solutions for Long-Term Relationships

This episode of Psych Hacks delves into the biological and psychological reasons why men often lose sexual interest in long-term relationships, primarily focusing on habituation and the Coolidge effect. Dr. Orion Taban explains that male sexuality, across the plant and animal kingdoms, is evolutionarily geared towards spreading genetic material widely, leading to a psychological apparatus that favors novelty. The Coolidge effect, illustrated by an apocryphal story involving President Calvin Coolidge, describes how males find novel sexual partners more attractive than familiar ones, a phenomenon much stronger in men than women.

The core argument is that sexually exclusive monogamy, while a societal norm, directly conflicts with this evolved male drive for novelty. Without the constant injection of newness, habituation sets in, diminishing sexual attraction. This isn't a sign of immaturity or toxicity, but rather an unconscious biological impulse serving the reproductive imperative, essentially telling a man's mind to seek new opportunities for genetic propagation. The podcast emphasizes the importance of understanding and accepting this reality rather than shaming it, as it's deeply linked to strategies for reproductive success.

Dr. Taban then proposes four distinct solutions for couples navigating this challenge in long-term relationships. The first is 'getting creative,' involving role-playing, costumes, or new environments to simulate novelty. The second, 'opening the relationship,' acknowledges that actual occasional novelty can sustain long-term commitment, referencing historical and non-Western cultural norms where the roles of wife and lover were often distinct. The third, 'carrying your cross,' is a more ascetic approach, advocating for the perpetual sacrifice of the desire for novelty on the altar of marriage, which can paradoxically lead to personal strength and 'neurotic productivity.'

The fourth and final solution, 'burying your libido,' is presented as a less desirable, yet prevalent, coping mechanism. This involves anesthetizing oneself with substances like TV, alcohol, or cannabis, overeating to lower testosterone, or resorting to furtive masturbation. This option represents a surrender to the inability to satisfy the desire for novelty, leading to a kind of psychological death. The episode concludes by inviting listeners to reflect on which solution is most common in contemporary society and its overall efficacy for both men and women, while also promoting the host's book, "The Value of Others," which explores these dynamics further.

Today, I'm going to be talking about another absolute killer of sexual attraction in men, which I'm calling habituation.

The cooage effect which has been established in not just human men but in males more generally is the psychological phenomenon that males find novel sexual partners more attractive than partners they have already slept with.

Without novelty, habituation starts to kick in, which kills sexual attraction in men.

But trying to shame this biological impulse as something toxic or immature in men is about as sensical as trying to shame women who demonstrate an urge to have children with their single best option.

The goal is to trick, at least partially and temporarily, a man's biology into thinking it's not [ __ ] his wife.

The chain of marriage is so heavy that it takes two to bear it, sometimes three.

That desire for novelty is going to be with you for as long as you live. Good. Keep the desire alive and perpetually sacrifice it on the altar of your marriage.

Nothing like sexual frustration for some good old-fashioned neurotic productivity.
