The False Equation#
The assumption that anatomy determines identity runs deep. It's baked into birth certificates, bathroom signs, medical intake forms, and countless casual conversations. When someone says "it's a boy" or "it's a girl" based on an ultrasound, they're not just describing anatomy—they're assigning a lifetime of expectations based on what they see between two tiny legs.
I remember the first time I consciously questioned this equation, though I'd been living its wrongness for years before I had words for it. I was maybe six years old, sitting in kindergarten, drawing stick figures of myself with exaggerated genitals because they felt so prominently wrong to me—this sense of wrongness that I couldn't articulate but felt compelled to express somehow. Those drawings got my parents called into the principal's office. Administrators assumed something concerning was happening at home. But there was no abuse to point to at that time. Just a five-year-old trying to communicate something about his body that nobody around him could understand, including himself.
The conflation of parts with identity has real consequences. It means that for many trans and nonbinary people, the journey toward bodily autonomy gets framed as "becoming" a different gender rather than simply becoming more yourself. It means that those of us who want to modify some aspects of our bodies but not others—or who want modifications that don't fit the standard narrative—face confusion, gatekeeping, and sometimes outright refusal of care.
The equation harms cisgender people too, though they may not recognize it as such. It's the same logic that says men shouldn't cry, that women belong in kitchens, that anyone who doesn't perform their assigned role correctly is somehow broken. The lie that body equals identity is the foundation of a whole system of constraint.
But the equation is a lie. And like all lies, it crumbles when you look closely at the evidence.
What the Evidence Actually Shows#
The distinction between biological sex and gender identity isn't new or radical—feminist scholars articulated it clearly in the mid-twentieth century, distinguishing between the physical features grouped under "sex" and the social roles, behaviors, and expectations we call "gender" (Oakley, 1972). What's become clearer in subsequent decades is that even the category of "sex" is more complex than the binary model suggests. Intersex variations—naturally occurring differences in chromosomes, hormones, gonads, or anatomy—are described differently depending on which traits and definitions a source counts (Fausto-Sterling, 2000). This guide does not use one contested prevalence estimate or a comparison with another trait to decide whether biological diversity matters.
The existence of intersex people doesn't just complicate binary categories—it reveals that those categories were always simplifications imposed on biological diversity rather than natural divisions discovered in nature.
Meanwhile, cultures around the world have recognized gender identities beyond the binary for centuries. Two-Spirit people in many Indigenous North American communities, hijra in South Asia, fa'afafine in Samoa—these aren't modern inventions or Western imports. They're evidence that human societies have always produced gender diversity, and that rigid binary frameworks are culturally specific rather than universal (Stryker, 2017). The Samoan fa'afafine, for instance, occupy a recognized social role that has existed for generations, demonstrating that gender categories are fundamentally social constructs that different cultures organize differently (Bartlett & Vasey, 2006).
The medical establishment has been slower to catch up, though it's moving. The World Professional Association for Transgender Health now explicitly states that "gender diversity is a natural variation in people and is not inherently pathological" (Coleman et al., 2022, p. S1). The ICD-11, effective since 2022, removed gender identity diagnoses from the mental health chapter entirely (World Health Organization, 2019). These aren't just symbolic changes—they reflect accumulating evidence that gender diversity is part of human variation, not a disorder requiring correction.
Genitals and Gender Identity#
Let's be direct about the body parts that often cause the most distress: genitals don't determine gender. A trans man with a vagina is still a man. A trans woman with a penis is still a woman. A nonbinary person with any configuration of anatomy is still nonbinary.
This might seem obvious stated plainly, but the cultural weight behind the genital-gender equation is enormous. We assign gender based on genitals at birth. We organize bathrooms, sports teams, and legal documents around assumptions about what's between people's legs. The entire edifice of binary gender rests on treating genitals as the definitive marker of who someone is.
But here's what I've learned from my own journey and from the hundreds of people I've talked with in the nullo community and broader trans world: what's between your legs tells you absolutely nothing about who someone is inside. I spent decades carrying genitals that felt fundamentally wrong—not because I wanted different genitals, but because I wanted none. That desire didn't make me less nonbinary. It made me more fully myself.
Sexual function and gender identity are also separate domains, though they're often conflated. Some people experience their genitals as essential to their sexuality; others experience them as irrelevant or even obstacles to sexual fulfillment. Some people pursue genital surgery to enable different kinds of sexual activity; others pursue it for reasons that have nothing to do with sex. There's no universal formula, and anyone who tells you your genitals must match your gender or your sexuality is working from assumptions, not facts.
Breasts, Chests, and Gender#
Chest dysphoria operates independently from other forms of gender-related distress. Some trans men experience intense dysphoria about their chest but feel comfortable with their genitals. Some nonbinary people want top surgery while keeping everything else unchanged. Some trans women deeply desire breast development while others are ambivalent about it.
The diversity of relationships people have with their chests illuminates how separating parts from identity actually works in practice. Consider that some cisgender men undergo gynecomastia surgery to remove breast tissue they developed during puberty—and no one questions whether that makes them "less male." Meanwhile, trans men seeking top surgery sometimes face interrogation about whether they're "really" trans, as if removing breast tissue is somehow a more serious modification requiring greater justification.
I've known people who identify fully as men and have chosen to keep their breasts. Their chests don't make them less men; they make them men with breasts. The chest tissue exists; the identity exists; the two don't need to align according to anyone else's expectations. One participant in a discussion I facilitated described it simply: "I'm a man. I have breasts. Those two facts coexist. They don't cancel each other out."
Beauty and identity intertwine here in complex ways. Cultural standards of attractiveness are heavily gendered, and many people feel pressure to modify their bodies to achieve certain aesthetic ideals associated with their gender. But you don't have to conform to any particular beauty standard to be valid in your gender. You don't need a "masculine" chest to be a man or a "feminine" figure to be a woman. Your body can look however it looks, and your gender is still real.
Secondary Sex Characteristics and Gender#
Hormones create changes, but they don't create gender. Gender exists before, during, and after any physical transitions.
This distinction matters because secondary sex characteristics—body hair, fat distribution, voice pitch, muscle mass, skin texture—are often treated as proof of gender rather than separate traits that happen to correlate with certain hormonal profiles. When someone's secondary sex characteristics don't match expectations for their gender, they face scrutiny, disbelief, and sometimes violence.
I continue testosterone because I like how I look and feel on it—the muscle definition, the body hair, the energy level. I also removed my genitals entirely. These aren't contradictions. They're the specific combination that makes me feel at home in my own body. Someone else might want the opposite: estrogen's effects on skin and fat distribution while keeping a penis. Another person might want no hormones at all while pursuing surgery. The variations are endless because people are endless.
What matters is recognizing that masculine or feminine traits are cultural constructs, not biological mandates. Having a deep voice doesn't make you a man. Having soft skin doesn't make you a woman. Bodies express hormonal environments and genetic inheritance; they don't express identity. Identity comes from somewhere deeper.
Bodies That Exist Beyond the Binary#
Abstract arguments only go so far. What really demonstrates the separation of parts from identity is the reality of people living in configurations that shouldn't be possible if the old equation were true.
Consider: there are people assigned male at birth who pursue genital nullification—the surgical creation of a smooth, flat genital area—while maintaining a masculine presentation and continuing testosterone. I'm one of them. The goal isn't to "become a woman" or even to appear more feminine. It's to have a body that finally feels congruent with an internal sense of self that was never well-served by having a penis and testicles. My gender expression hasn't changed. My pronouns haven't changed. What's changed is that I no longer carry anatomy that caused me daily distress.
Consider: there are men—people who identify fully and completely as men—who have vaginas. Some are trans men who haven't pursued or don't want phalloplasty. Others have undergone vaginoplasty while continuing testosterone because that combination of anatomy and hormonal profile feels right to them. Having a vagina doesn't make them less men. It makes them men with vaginas.
Consider: there are people pursuing "mixed-presentation" configurations that deliberately combine elements traditionally associated with different genders. Phallus-preserving vaginoplasty. Vagina-preserving phalloplasty. Breast augmentation while keeping a penis. Top surgery while keeping a vagina. These aren't compromises or incomplete transitions. They're precise expressions of what specific individuals actually want their bodies to be.
The surgeons who perform these procedures are increasingly explicit about their willingness to work with patients whose goals don't fit standard narratives. Some surgeons publicly discuss nonbinary surgical approaches, including Dr. Keelee MacPhee (MacPhee, 2024). Provider materials can describe a clinician's stated practice; they are not independent evidence of outcomes or availability. This isn't fringe medicine. It's the leading edge of a field that's finally recognizing what patients have been saying for decades: we know what we need, and our needs don't always match your categories.
Parts That Cause Dysphoria#
Dysphoria is specific and personal. You don't need to experience dysphoria about every gendered aspect of your anatomy. Many people feel intensely distressed about some body parts while feeling neutral or even positive about others. That specificity is information, not a problem to explain away.
For me, the dysphoria was always genital. Always. As far back as I can remember, something about that part of my body felt fundamentally wrong—alien, not-mine, a constant source of low-grade dissonance that colored every day. My chest? Fine. My voice? No problem. My facial hair? I actually like it. But those other parts... that was different. That was unbearable in a way that's hard to describe to someone who hasn't experienced it.
Dysphoria can be about appearance, about function, about sensation, or about something harder to name. Some people hate looking at certain body parts. Others don't mind the visual but hate the physical sensations. Still others experience dysphoria mainly in sexual contexts, or mainly in social contexts, or mainly in private moments alone. The specific texture of your distress is yours, and you don't need to justify it by making it legible to others.
This specificity also means you have permission to target specific procedures. You don't need to pursue every surgery that's available or that's "typical" for someone with your identity. You can choose the modifications that address your specific dysphoria and skip the ones that don't matter as much to you. The goal is feeling at home in your body, not checking boxes on someone else's transition checklist.
Sexuality and Parts#
Your genitals don't determine your sexuality, and your sexuality doesn't determine what genitals you should have.
This might seem obvious, but it's worth stating explicitly because so many assumptions get tangled together. Some people assume that trans women who are attracted to women must not "really" be trans. Others assume that people who pursue genital surgery must be heterosexual in their post-surgical orientation. None of these assumptions hold up.
I've met gay trans men who have vaginas and love their vaginas. I've met lesbian trans women who have penises and have no plans to pursue vaginoplasty. I've met asexual people who pursued genital surgery to eliminate a source of dysphoria that had nothing to do with sex. I've met people whose sexuality shifted during or after transition—and people whose sexuality stayed exactly the same.
For me, becoming a nullo hasn't changed my orientation or my interest in intimacy. What it's changed is my ability to be present during intimacy without the constant background noise of genital dysphoria. Sex is better now, not because my anatomy is "better," but because I can actually inhabit my body during it.
Sexuality can also shift with transition, and that's okay. Some people discover attraction patterns they didn't know they had once they're more comfortable in their bodies. Others find their existing attractions intensify or clarify. Still others experience no change at all. There's no universal trajectory, and there's no right answer. Your sexuality is yours to discover and express however it manifests.
When Your Parts Don't Match Your Gender#
This is normal. This is so normal it's almost universal among trans and nonbinary people, at least at some point in our journeys.
The mismatch between internal sense of self and external anatomy is often what drives people toward this book in the first place. You know who you are. You look down at your body, or you catch a glimpse of yourself in the mirror, and something doesn't line up. That gap can be painful, exhausting, and difficult to bridge.
But here's what I want you to know: there is no "correct" trans body. There is no configuration you need to achieve to be valid in your identity. Medical autonomy includes the right to keep parts you want to keep, even if others expect you to modify them. It includes the right to pursue changes others might not understand. It includes the right to integrate whatever body you have or choose with whatever identity you hold.
I spent years thinking surgery wasn't for me because I didn't want vaginoplasty—and at the time, that seemed like the only option for someone assigned male at birth who experienced genital dysphoria. Finding the nullo community, finding out that nullification existed and was actually available, changed my understanding of what was possible. Suddenly there was a path that made sense for my specific body and my specific identity.
Nonbinary configurations are valid. Bodies that don't fit neatly into "male" or "female" categories are valid. Your body, whatever form it takes or you choose for it, is valid.
Body Autonomy Across the Spectrum#
Surgery is a choice, not a requirement. No transition is incomplete without surgery—or with it, for that matter. Your path is valid even if it looks nothing like anyone else's.
This principle applies across the full spectrum of choices. Some people need surgery to survive. I was one of them; the dysphoria was that intense, that constant, that destructive. But other people manage their dysphoria through non-surgical means, or don't experience enough distress to warrant surgical intervention, or simply don't want to modify their bodies surgically even if they could. All of these approaches are valid.
The danger lies in comparing your insides to someone else's outsides. You might see someone who's had surgery and seems happy, and assume you need the same surgery to achieve the same happiness. Or you might see someone who hasn't had surgery and seems comfortable, and assume there's something wrong with you for wanting it. Neither comparison serves you. The only relevant question is what you need to feel at home in your own body.
You also have permission to change your mind. Maybe you were certain you wanted a procedure, and now you're not. Maybe you thought you didn't want surgery, and now you do. These shifts don't invalidate your earlier positions or your current ones. People evolve. Bodies change. Desires clarify. The journey isn't a straight line from confusion to certainty; it's more like a spiral, returning to similar questions with different perspectives as you grow.
The Language We Use#
Part of breaking the equation is finding language that actually fits. The words we inherit are often inadequate—clinical terms like "penectomy" describe procedures but don't capture meaning, while gendered terms like "women's health" exclude people who have the relevant anatomy without the assumed gender.
Within trans and nonbinary communities, people have always created their own vocabulary. "Nullo" emerged from community forums and whispered conversations, not medical journals. "Pussyboy," "dickgirl," and dozens of other terms—some reclaimed, some invented—exist because people needed ways to describe experiences the mainstream vocabulary couldn't hold.
You get to choose what words you use for your own body. You get to decide whether clinical language, community language, or something entirely personal fits best. You're not obligated to use any particular term just because a doctor prefers it or because it appears on a form. If no existing word captures your experience, you can make one up. Your body, your vocabulary.
This extends to how you describe your goals and your identity. You don't have to fit your experience into someone else's narrative to make it legible. If "trans" feels right, use it. If "nonbinary" fits better, use that. If nothing in the existing lexicon works, you're allowed to simply describe what you want and who you are without forcing it into established categories.
I've used various terms for myself over the years—nonbinary, genderqueer, transmasculine-adjacent, just plain queer. Currently "nonbinary nullo" captures it well enough, though I hold these labels loosely. What matters more than the words is whether they help you communicate clearly about what you need.
Navigating a Binary World#
The freedom to define your own body and identity doesn't mean the world will immediately understand or cooperate. Healthcare systems, legal documents, family members, and random strangers all have expectations shaped by the old equation. Navigating these systems while living outside their assumptions requires strategy and resilience.
With healthcare providers, the most important thing is finding people who will work with you rather than try to fit you into their preexisting frameworks. This may take some searching. Many providers, even well-intentioned ones, were trained in binary approaches and may struggle with goals that don't match the standard scripts. Some will ask why you want a particular procedure without others in the "typical" sequence. Some will question whether you've "really thought this through."
I got lucky. The surgeon who performed my nullification understood immediately what I wanted and why. But I've heard from countless others who faced repeated gatekeeping, who were told their desires didn't make sense, who had to educate their own doctors about what was possible. If you encounter resistance, know that the resistance says more about the limitations of the system than about the legitimacy of your needs.
The shift toward informed consent models is helping. Under informed consent, you don't have to prove your identity to a gatekeeper's satisfaction—you make decisions about your own care after receiving relevant information about risks, benefits, and alternatives. The provider's role becomes supporting your autonomy rather than validating your claims (Cavanaugh et al., 2016). Not all providers operate this way yet, but the field is moving in this direction, and seeking out informed-consent-friendly practitioners is often worth the effort.
With family, friends, and others in your life, you get to decide how much to explain and to whom. You're not obligated to educate everyone you encounter or to justify your choices to people who aren't willing to understand. Some people will surprise you with their acceptance. Others will disappoint you. Many will simply need time and repeated exposure to adjust their assumptions.
One approach that often works: frame your choices in terms of your own wellbeing rather than abstract gender theory. "This brings me peace" is harder to argue with than "gender is a social construct." People who love you generally want you to be okay, even if they don't fully understand why this particular change matters.
The Right to Define Yourself#
Underlying everything in this guide is a simple principle: you have the right to define your own body, your own identity, and your own path. This isn't a privilege to be earned by meeting certain criteria or performing your gender correctly according to someone else's standards. It's a fundamental aspect of human dignity.
The United Nations explicitly recognizes access to transition-related medical care as part of bodily autonomy for trans people (Office of the United Nations High Commissioner for Human Rights, 2021). Major medical organizations describe gender-affirming care as individualized care (Coleman et al., 2022). Green et al. concerns gender-affirming hormone therapy among youth, not surgical regret. Bustos et al. addresses regret after gender-affirmation surgery, but its pooled literature and procedure mix do not establish an outcome for every person or procedure. Keep access, mental-health associations, and procedure-specific surgical outcomes separate rather than using either study as a universal promise (Green et al., 2022; Bustos et al., 2021).
You don't need anyone's permission to know what you need. You don't need to justify your desires to be worthy of care. You don't need to fit a particular narrative or present a particular way or use particular words.
Your body belongs to you. What you do with it is your choice. And that choice can include modifications that don't make sense to anyone else but make perfect sense to you.
Identity Beyond Surgery#
Surgery can change how you move through the world. It can alleviate dysphoria, enable different forms of expression, open possibilities that weren't available before. But surgery doesn't change who you are at your core.
This cuts both ways. It means that if you pursue surgery, you'll still be you on the other side—with all your complexities, your relationships, your history. Some people expect surgery to solve problems it can't solve. They hope that once their body is "fixed," everything else will fall into place. It doesn't work like that. Surgery addresses physical dysphoria; it doesn't automatically repair damaged relationships, resolve trauma, or create meaning.
It also means that your gender doesn't need surgical proof. You don't have to undergo any particular procedure to be valid in your identity. The relationship between your body and your gender is yours to define. Some people need surgical intervention to survive; others don't. Neither experience is more legitimate than the other.
Post-surgery identity questions are normal. You might find yourself re-examining aspects of your gender that you thought were settled. You might discover that with certain dysphoria resolved, you have more capacity to explore other aspects of yourself. You might feel momentary confusion about how you fit into categories you previously felt certain about. This is all part of the process.
Your identity will continue to evolve after surgery, just as it evolved before. Bodies change; identities deepen; understanding clarifies over time. The person you are five years post-op will be somewhat different from the person you are today, and that's how growth works. Surgery is a milestone, not a destination.
What Comes Next#
This guide has laid the philosophical groundwork: parts don't equal identity, and you have the right to shape your body according to your own understanding of what home means. The guides that follow will move into more practical territory—specific surgical options, how to evaluate surgeons, preparing for procedures, navigating recovery.
But before we get there, I want you to sit with what we've covered. The freedom this guide describes can be overwhelming. If you've spent years trying to make yourself fit into boxes that weren't designed for you, the sudden realization that the boxes are optional might feel disorienting rather than liberating. That's okay. You don't have to figure everything out immediately.
What I hope you take from this guide is possibility. Not a prescription, not a particular path you should follow, but the knowledge that the range of options is wider than you may have been told. People like you have made choices like the ones you're considering. They're living full lives in bodies that work for them.
You can too.
Reflection Questions#
What assumptions about the relationship between anatomy and identity have shaped your understanding of your own possibilities? Which of those assumptions, if any, are you ready to question?
If you could design your body purely based on what would bring you comfort and peace—setting aside what's "normal" or expected—what would that look like? Be as specific as you can.
What words do you currently use for your body and your identity? Do they fit, or are they approximations? What might fit better?
Who in your life would you want to understand your choices, and what would help them understand? Who, if anyone, might you need to stop trying to convince?
What's one thing you learned in this guide that expands what you thought was possible for yourself?
