In this episode of Modern Wisdom, featuring Chris Williamson and Dr Robert King, Why Does The Female Orgasm Exist? - Dr Robert King explores why Female Orgasm Exists: Biology, Choice, and Sexual Politics Unpacked Dr. Robert King challenges the long-standing notion that female orgasm is a useless evolutionary byproduct, arguing instead that it has clear adaptive roles linked to fertility and mate selection.
Why Female Orgasm Exists: Biology, Choice, and Sexual Politics Unpacked
Dr. Robert King challenges the long-standing notion that female orgasm is a useless evolutionary byproduct, arguing instead that it has clear adaptive roles linked to fertility and mate selection.
He contrasts lab-based, decontextualized sex research with more ecologically valid studies that show orgasm-related oxytocin and uterine contractions can aid rapid sperm transport and conception.
King explains how female orgasm, desire, and even faking orgasm function as complex signals within sexual selection, deeply shaped by female choice, partner traits, and cultural pressures.
The discussion broadens into modern sexual culture, female intrasexual competition, porn and fantasy, hormonal birth control, and the demographic implications of shifting mating patterns.
Key Takeaways
Female orgasm likely has adaptive reproductive functions, not just pleasure.
Evidence from human and animal studies shows orgasm-triggered oxytocin release and uterine peristalsis can reduce semen backflow and aid rapid sperm transport, increasing odds of conception.

Most earlier ‘female orgasm does nothing’ theories relied on flawed assumptions and narrow data.
Byproduct theories treated the clitoris as a trivial ‘female nipple’ and leaned heavily on constrained lab masturbation studies, ignoring anatomical data and more naturalistic partner-sex research showing fertility-linked mechanisms.

There appear to be at least two broad experiential types of female orgasm.
Survey and factor-analytic work suggests ‘surface’ orgasms (more intense, externally felt) and ‘deep’ orgasms (internally felt, more associated with oxytocin-like sensations such as floatiness, trust, and breath changes), without implying any are more ‘mature’ or ‘healthy’.

Partner traits strongly predict orgasm likelihood, and they’re not the obvious ones.
Women in studies reported higher orgasm rates with partners who smelled particularly attractive (implying genetic compatibility), were sexually dominant yet considerate, paid close attention, and provided deep, vigorous penetration; height, money, and generic muscularity did not show strong predictive power.

Faking orgasm is a strategic signal, not just politeness or ego-soothing.
Seen through signaling theory, faked orgasms can falsely signal commitment, satisfaction, or fertility to a partner and to onlookers, analogous to fake laughter signaling acceptance or status; it complicates male inference about their own sexual performance and relationship security.

Female sexual selection and intrasexual competition quietly shape much of human mating behavior.
Women compete subtly via tactics like moralized gossip (“venting”), signaling sexual restraint, or status-markers like luxury handbags, while choosing men partly by how other women desire them (sexy-son dynamics) and how well men invest—often invisible to men who misread female competition.

Modern sexual culture may be undermining stable mate choice and satisfaction.
Social media and dating apps expand perceived choice to thousands of potential partners, potentially making female selection computationally overwhelming, lowering commitment, feeding demographic decline, and interacting with hormonal birth control in ways we barely understand—especially around attraction and orgasm patterns.

Notable Quotes
“Female orgasm’s supposed ‘inefficiency’ is really just a sign that women are being extremely picky.”
— Dr. Robert King
“The clitoris isn’t what you think it is… it’s about four inches long, mostly internal, and nothing like a male nipple.”
— Dr. Robert King
“Once oxytocin levels are raised, those pressure changes persist for quite a while—it’s not just the pleasurable moment when the ‘insuck’ happens.”
— Dr. Robert King
“We need to stop having sex with the psychopaths.”
— Dr. Robert King
“It really just is female selection all the way down.”
— Dr. Robert King

How do you get into studying the female orgasm?
(laughs) Um, let's just go, go, get, dive straight in. Um, okay. So my background was, I was a school teacher for 20 years. Um, and I, uh, was interested in psychology and maths. That's what I taught. About 20 years ago, I came across a really interesting book by a woman called Elizabeth Lloyd. Uh, it was, uh, uh, A Bias in the Science of, uh, of Evolution. I was on holiday in Thailand. Uh, I read it. Um, the book told me that female orgasm did nothing, uh, had no function. And, uh, to say I was, I was surprised would be, uh, an understatement. And, uh, I, I just, I got interested, and I started studying evolutionary biology. And I approached, uh, some prominent figures in the field and said, "I think I have an i- you seem to have an issue here, uh, studying this subject, I think..." Um, and it, it, it, um, you know, just sort of, I, you know, I'm obviously quite a, a nerdy kind of character. I, I delve into these things. I read the original stuff. And once I started reading the original stuff, it became obvious that there were two very distinct traditions of, of studying, um, human sexuality, particularly female orgasm. One of them, uh, went down this, this strange route of saying it did nothing, and another one, which had been somewhat, uh, sidelined, uh, suggested it actually had some really interesting functions. So like-
What was your-
Uh-
W- w- what was your intuition? What was it that you thought early on, "Huh, this, this seems to be a fruitful area to research more into"?
Um, it, it became obvious from a fairly early stage that a number of the people who were opining about, about female orgasm, we're not studying sex at all. Uh, not in any kind of, you know, sense of, of actually being in the room with other people having sex. Uh, that's, that's why I start off the book by talking about, uh, animals in zoos and, uh, mating in captivity because what was being studied in laboratories just felt a lot like studying mating in captivity. And that doesn't, doesn't capture the, the range of, uh, what humans are up to or interested in. It doesn't capture the range of what other animals are interested, uh, makes them interesting either to be honest. Uh, um, I mean, it's, you know, it... That's, that's why I start off the book talking about COVID and the fact that... Uh, I, I live next to Fota, which is a terrific, um, uh, wildlife park, and I recommend it highly. And we have the, uh, the breeding, uh, group of, of a number of animals, uh, giraffes, uh, cheetahs. We've got some new tigers there. What else have we got? Uh, lions. And they've all had babies. And one of the reasons they have babies is because they have privacy. Uh, they can hide away from humans when they don't, don't want to play with us and do want to play with each other.
