I need to address something that has become strangely controversial: the reality of biological sex.
We live in an era where even the most basic observations about men and women have become politically charged. Some argue that all differences between the sexes are cultural constructs. Others weaponize biology to enforce rigid roles. Both extremes miss the point, and both make it harder to understand what actually creates attraction and sustains intimacy.
So let's be clear about what we know.
Men and women are different.
Not just culturally different. Biologically different. Measurably, observably, consequentially different.
These differences are not small. On average, men are taller and have roughly 60% more upper body strength than women. Men will never ovulate, gestate, lactate, menstruate, or go through menopause. Women will never produce sperm. These are not social constructs. They are the result of millions of years of sexual selection.
As evolutionary biologists Heather Heying and Bret Weinstein write in A Hunter-Gatherer's Guide to the 21st Century:
"Differences between the sexes are a reality, and while they can be cause for concern, they are also very often a strength, and we ignore them at our peril."
This isn't ideology. It's observation. And far from being oppressive, understanding these differences is liberating, because it allows us to work with our nature rather than against it.
Women, who bear the enormous biological cost of pregnancy and nursing, evolved to be more selective about their mates. Men, who can theoretically father unlimited offspring, evolved with different reproductive strategies. Neither approach is better or worse. They're complementary: two halves of a species-wide strategy that has proven remarkably successful.
These differences show up everywhere once you look for them: in what attracts us, in how we communicate, in what makes us feel loved, in how we experience desire. Pretending they don't exist doesn't make them disappear. It just makes them confusing.
Now, the words masculine and feminine are not based on biology. They are cultural concepts. And the distinction matters more than most people realize.
The historian Yuval Noah Harari offers a powerful framework in Sapiens. His rule of thumb for separating biological reality from cultural myth:
"Biology enables. Culture forbids."
What does this mean?
Biology doesn't dictate behavior. It creates a vast range of possibilities. Culture then steps in and decides which of those possibilities are encouraged, tolerated, or forbidden.
Biology enables women to have children. Some cultures treat this as a sacred choice; others treat it as an obligation. Biology enables men and women to form countless configurations of relationship and desire. Some cultures celebrate this diversity; others restrict it violently.
Harari takes this further. A truly unnatural behavior, one that genuinely goes against the laws of nature, simply cannot exist, and so it would need no prohibition. Biology has no concept of "natural" or "unnatural."
Organs evolve for one function and get repurposed constantly. Mouths evolved to eat. Now we use them to kiss, to speak, to moan in pleasure. Sex evolved for procreation. Now we use it to bond, to heal, to touch the divine.
None of this is unnatural. All of it is what biology enables.
And this is where the distinction between sex and gender becomes crucial.
Sex is a biological category: male or female, determined by chromosomes and reproductive anatomy. It is objective and constant. Gender is a cultural category: what a given society considers "manly" or "womanly." It is imagined, and it shifts constantly.
The cultural concepts of masculine and feminine imply that your manhood or womanhood is something you must earn, and therefore something that can be taken away.
Males must prove their masculinity constantly. Women must continually convince themselves and others that they are feminine enough. But no one can take away the fact that you are a man or a woman. That's biology. And biology doesn't need to be earned.
This is why we don't use masculine and feminine as our framework. The words carry centuries of cultural baggage that obscures the deeper reality we're trying to reach.
For now, understand this: our biology gives us capacities, for aggression and for tenderness, for competition and for cooperation, for dominance and for surrender. Which capacities we express depends on culture, on circumstance, on individual choice.
Men and women are biologically different. And within those differences, there is vast individual variation. Some men are more nurturing than most women. Some women are more competitive than most men. Biology provides tendencies, not destinies.
And what this means for your sex life: your desire is not broken. Your partner's desire is not broken. The ways you each approach intimacy, the differences that sometimes feel like incompatibilities, are often just biology expressing itself. Understanding this can transform frustration into curiosity.
The key is to honor the general patterns without imprisoning individuals within them.
Sometimes, when people notice that attraction has faded, they often reach for a simple solution: "Men need to be more masculine. Women need to be more feminine. If we just return to traditional gender roles, everything will work."
It sounds logical. And there's a half-truth in it. Polarity does create attraction. Difference does generate spark.
But if this were the whole answer, previous generations wouldn't have struggled with the same problems we do. If simply being "more masculine" or "more feminine" solved the issue, then every era before ours, when gender roles went unquestioned, would have been a paradise of passionate marriages.
It wasn't.
The battle of the sexes is as old as recorded history. Complaints about unresponsive husbands and nagging wives appear in ancient texts. Sexless marriages, infidelity, resentment, and quiet desperation are not modern inventions. They've been with us all along.
Why?
Because "be more masculine" and "be more feminine" are scratching the surface of something much deeper. Gender is just the outermost layer of a reality that runs all the way to the core of existence.
We know this firsthand. When we first started teaching, we used the words masculine and feminine ourselves. It was the language we'd inherited, and for a while it seemed to work. But the deeper we went, the more the framework strained. Londin would be firing on all cylinders, running a business, holding space in client sessions, leading with the sharpest mind in the room, and the old model had no name for what she was doing except "masculine." As if the very qualities that made her extraordinary somehow made her less of a woman.
The labels didn't just fall short. They started doing damage. We needed a language that honored the depth of what we were discovering without forcing it through a gendered filter. That's when Alpha and Omega emerged, not as a rebranding, but as a recognition that what we were actually working with had never been about men and women. It was about something far more fundamental.
If we want access to the kind of polarity that doesn't just create spark but sustains it for decades, that keeps the bedroom alive year after year, we have to go beyond gender altogether. We have to understand what masculine and feminine are actually pointing to at the deepest level.
