Why Would Any Man Choose To Be Cucked? - Dr David Ley

Chris opens by naming the contradiction that organises the episode. A partner being intimate with another man "should evolutionarily be one of the biggest fears in a man's life", yet encouraging it has become a recognisable pursuit with its own vocabulary, its own porn category and, according to his guest, its own literature. The framing matters: this is not a curiosity segment about a fringe fetish but an attempt to explain why a behaviour that looks like the negation of male interest attracts an ordinary population.

The guest is David Ley, a clinical psychologist and Sexual Health Alliance board member whose research sits at the intersection of sexuality, pornography and mental health. Chris concedes he cannot project himself into the mindset, and says the explanation "at least begins to illuminate what might be going on at the moment".

Ley's route in was not intellectual. Around 2007 he was depressed and running a large community mental health agency — Medicaid billing, HR, budgets — and he began collecting data for a study of consensual non-monogamy as a way of working on something that interested him while his day job drained him. The study was never published; he calls it "a crappy little study, probably not very good".

Inside that fieldwork he met two couples living what he calls the cuckold or hot-wife lifestyle, where the wife was enthusiastically sexual with men outside the relationship and the husband was monogamous. His first reaction was blunt: "wow, that's crazy. That can't work." What unsettled him was the follow-up: both couples had been married for decades, had successful careers, children and, by his own clinical yardsticks, excellent communication.

That mismatch forced him to interrogate his own reaction rather than the couples. He concluded that, without noticing it, he had been importing moral biases about female sexuality, promiscuity and monogamy into clinical judgement, biases nobody had trained him to audit. In the literature he found almost nothing: a single 1990s study by an Israeli psychologist analysing letters to Penthouse about wife sharing.

From there he built the missing literature himself, drawing on evolutionary psychology, the psychology of monogamy, the biology of sexuality and female sexual arousal, and pairing it with interviews with people living the arrangement worldwide. His conclusion was that clinicians like him assumed the practice was pathological mainly because "they'd never been taught how diverse sexuality is" — an indictment of training, not of patients.

The timing is part of the story. When Ley wrote the book, "nobody was really talking about Cuckolding, but over the past few years, it's really exploded", helped by high-profile scandals and by pornography, where it is now a major category. The audiobook edition, he notes with some satisfaction, is selling strongly on Audible.

Chris then poses the question the audience is actually asking: how does a man get past the fear that evolutionary psychology says should be central to him? He is explicit that he expects most listeners to be thinking "fuck no". If male parental uncertainty is wired in as something "we are incredibly scared of", then widespread enjoyment of the scenario is not a small anomaly — it is a contradiction that needs explaining.

Ley agrees it is worth studying and admits the field has no answer. The comparison case is stark: for many men the fear of a partner's infidelity triggers rage, and "Fear of infidelity is really common in spousal homicide." Yet other men are aroused by the same prospect. What separates them is, in his words, simply unknown. His speculations — openness to experience, an overlap with kink, an interest in submission in the bondage-and-discipline sense — are offered as speculations, and he says they do not cover all of these men.

His most counter-intuitive claim is about socialisation. Men raised in rigidly masculinised environments are, he says, more likely to be aroused by the idea, because the fantasy functions as an exit from a rule they have been living under.

in order to be a man, you know, you must be so manly that your wife would never even want another man

On that reading, cuckolding is less a rejection of masculinity than a holiday from its enforcement: the pressure is a burden, and watching from the side is a lower-pressure position. He adds that the fantasy appears more common among Republicans than Democrats and more prevalent in macho societies such as Brazil and Russia, though the base is self-report and, as the host notes, no better instrument obviously exists.
