What Is Gender Identity? Gender as a Spectrum and Its 4 Axes
Gender isn't just male and female; it's made up of several separate axes. Once you understand them, you understand yourself and the people around you better.
Key points
- Gender has at least four separate axes: sex characteristics, gender identity, gender expression and sexual orientation.
- Gender identity is something a person tells you themselves, not something others guess or decide for them. If you're unsure, it's fine to ask politely.
- Gender diversity is not an illness, but if incongruence causes distress, a doctor can help.
Self-check: the 5 dimensions of sex and gender
Move each slider to where you are. The 5 dimensions are independent: someone assigned male may identify as a woman, express any style, and be attracted to anyone. 0 is the middle or both equally. There is no right or wrong answer. Nothing is sent or saved.

Your profile
This is a self-reflection tool, not a diagnosis. Gender isn't two fixed boxes; each axis is independent and can change over time. If your body or gender causes you distress, or you'd like to talk about hormones, a doctor can help without judgement.
Adult gender incongruence self-check (based on DSM-5-TR)
Tick what fits you. This is a plain-language paraphrase of the DSM-5-TR criteria for gender dysphoria in adults, for self-understanding only. It is not a diagnosis, and you don't need to pass any test to be who you are. Nothing is sent or saved.
Your gender identity doesn't need any questionnaire to be valid. If you have thoughts of harming yourself, call Thailand's 24-hour mental health hotline 1323 (Thai; ask for English support) or 1669 in an emergency.
When someone asks me, "Doctor, is that person a man or a woman?" I usually reply, "Why not ask them?" I'm not dodging the question. Gender identity lives on the inside, and the person who knows it best is the person themselves. Guessing from someone's face, voice or clothes is often wrong and can hurt the person in front of you without meaning to.
This article explains how gender has several axes, why they don't have to line up, and how to communicate respectfully with the people around you.
What is gender identity?
Gender identity is your inner sense and awareness of "what gender I am". It may be man, woman, both, neither, or something that shifts. This identity doesn't have to match the sex recorded at birth.
- People whose identity matches their sex assigned at birth are called cisgender.
- People whose identity differs from their sex assigned at birth are called transgender, for example trans women and trans men.
- People who don't fit within the man/woman framework may describe themselves as non-binary or with other words; see non-binary, agender and pangender.
The 4 separate axes of gender
Picture four sliders, each moving independently.
| Axis | Question it answers | Examples |
|---|---|---|
| Sex characteristics | What chromosomes, hormones and genitals does the body have? | Male, female, intersex |
| Gender identity | Who do I feel I am inside? | Man, woman, trans, non-binary |
| Gender expression | How do I present myself to the world? | Clothing, hairstyle, mannerisms, voice |
| Sexual orientation | Who am I attracted to? | Men, women, more than one gender, or no sexual attraction (asexual) |
Even sex at birth isn't strictly two categories: some people are born with variations in sex characteristics (intersex, or differences of sex development, DSD).
Sex assigned at birth
What the body is like
- Male
- Female
- Intersex
Gender identity
Who I am inside
- Man, woman
- Trans
- Non-binary
Expression
How I present to the world
- Clothes, hairstyle
- Manner, voice
Sexual orientation
Who I am attracted to
- Men, women or both
- Asexual
Don't guess one axis from another.
Examples to help picture it
- Someone born with a male body who feels she is a woman, dresses as a woman and is attracted to women might describe herself as a trans woman who is lesbian.
- A cisgender man attracted to men who dresses plainly and looks "masculine" can be gay, and a gay man who is camp is still a man too (see top gay men don't have to be macho).
- A woman who likes wearing suits and short hair doesn't necessarily want to be a man. Expression is separate from identity (see genderless fashion).
The key point: don't guess one axis from another.
How to ask about pronouns politely
Thai has the advantage that many pronouns are already neutral, such as "khao" (he/she/they), "rao" (we/I) and "khun" (you). But the polite particles "khrap" (used by men) and "kha" (used by women), and terms like "phi chai" (older brother) or "phi sao" (older sister), do signal gender. In English, the equivalent is choosing he, she or they.
- If you're not sure, use the person's name or neutral words for now.
- You can ask directly but politely, for example, "What would you like me to call you?"
- If you get it wrong, apologise briefly and correct yourself; no need for a long explanation.
- Don't ask about genitals, surgery or a former name unless it's necessary and they've raised it themselves.
In the clinic, I always ask what name and pronouns people would like me to use, because feeling safe from the very first minute is what makes people comfortable telling me about their real health problems.
- 1Unsure? Stay neutralUse their name or words like "they" or "you" for now
- 2Ask directly but politely"What would you like me to call you?"
- 3Got it wrong? Brief apologyThen correct it; no long explanation needed
- 4Respect privacyDon't ask about genitals, surgery or former names
Gender diversity is not an illness
In 2019, the World Health Organization moved "gender incongruence" in ICD-11 out of the mental disorders chapter and into the chapter on conditions related to sexual health. The DSM-5-TR (2022) uses the term gender dysphoria to mean the distress caused by that incongruence, not the identity itself.
This means being trans or non-binary is not a sickness. But if the mismatch between body and identity causes distress, medical care such as counselling or gender-affirming hormone therapy can help.
Respect is the baseline, not a special privilege
Teasing, joking or bullying about gender may seem like small jokes, but for people who face it again and again, it builds up into chronic stress and is linked to higher rates of depression and self-harm thoughts. Being respectful isn't just good manners; it's a health issue too.

When to see a doctor or sexologist
- You feel confused or distressed about your identity to the point that it affects study, work or sleep.
- You want to start hormones, or are using hormones you bought yourself.
- Your family or partner doesn't understand and you'd like someone neutral to help you talk.
- You have thoughts of harming yourself (call 1323, Thailand's free 24-hour mental-health hotline; Thai language, ask for English support).

Frequently asked questions
What is the difference between gender identity and sexual orientation?
Gender identity is "who I am"; sexual orientation is "who I'm attracted to". They are separate. For example, a trans woman may be attracted to men, women or both.
Can gender identity change?
For many people it stays stable throughout life, but some discover themselves later, or feel it shifts (genderfluid). Both are normal. No one can force an identity to change, and attempts at "conversion therapy" have been shown to be harmful.
What should I do if I use the wrong pronoun?
Apologise briefly, correct yourself and carry on as normal. There's no need for a long explanation or to make it a big deal. Intending to get it right next time is what matters most.
Is being trans a mental illness?
No. The World Health Organization removed gender incongruence from the mental disorders chapter in ICD-11. What doctors care for is any related distress or medical need.
