    Is your gender identity fixed, or can it change over time? Some people experience a form of gender fluidity. Let’s explore what that means.

    Terminology

    Here are some terms relating to gender identity and gender fluidity that are important to know.

    Gender Identity

    Gender identity is each person’s internal sense of their gender. It is how they perceive whether they are a man, woman, non-binary, or something else. Each person’s gender identity is an important part of their overall persona and should be respected.

    Gender Expression

    Gender expression refers to how a person expresses that gender to the world. Gender may be expressed through clothing, mannerisms, makeup, or hairstyles.

    Gender Binary

    This is the concept that there are only two genders – man and women. Most scientists and sociologists have rejected the binary gender assumption in favor of a gender spectrum.

    Gender Spectrum

    This is the concept that gender identity exists on a spectrum that includes man and woman, but also non-binary genders.

    Gender Fluidity

    Refers to the belief that some people have a fluctuating gender identity. This means their gender identity may change over time rather than remaining a particular gender.

    Non-Binary

    An umbrella term for gender identities that are not specifically within the binary gender classification of man or woman.

    Gender Affirming Care

    Any medical care provided to help affirm a person’s gender identity.

    AFAB/AMAB

    Assigned female at birth or assigned male at birth. This is an assignment based on biological sex using the infant’s external anatomy. In Western societies, biological sex is usually used as a presumptive factor for the infant’s gender identity.

    History

    The concept of gender fluidity or fluctuating gender is fairly new. Its history is tied in with discourse on gender identity, gender expression, and traditional gender norms.

    Concepts like gender fluidity and gender identity have evolved over time to challenge society’s traditional notion that male and female are the only gender identities. Historically, society’s expectations have tied a person’s gender identity to their sex assigned at birth. We have only recently begun to recognize gender identity as something that cannot simply be assigned based on biological sex markers. Despite this, non-binary identities that include those who identify as multiple genders, no gender, or a third gender have always existed. They have even been recognized within some cultures.

    Non-binary individuals include those who are gender fluid, identify with third genders, or as Two-Spirit in Indigenous cultures have always existed, and may express their gender in ways that don’t align with social norms. With the adoption of these terms in mainstream, gender fluidity is becoming more accepted. Even pronoun usage has evolved as a way to respect a person’s gender identity even when that doesn’t align with a limited male or female dichotomy.

    Academic institutions like the Williams Institute and research scholars like Katz-Wise have engaged in significant study, research, and discourse on gender identity, especially as it relates to the queer community. This includes how transgender people, face discrimination and abuse when their gender expression doesn’t align with mainstream expectations. This is something that impacts transgender youth.

    The existence of intersex people who have sex characteristics that don’t align with male and female provides further proof that gender identity and even biological sex are not as easily assigned and categorized as some may insist. Gender is complex and cannot be forced into binary classifications. This is why the term non-binary works so well as an umbrella term that encompasses a diversity of gender identities.

    Flags & Symbols

    There are several flags that represent gender identity, including those who are gender fluid or have non-binary identities.

    Is My Gender Fluctuating?

    If you are questioning your gender, know that you are not alone. Our understanding of gender, including our own identity can evolve over time. Some people may be well into adulthood before they find an identity that fits them. As part of that process, you may find that you fluctuate between more than one gender or even three or more genders.

    This can be jarring if you have always assumed your sex assigned at birth and gender would be aligned. Despite this, learning your true gender identity and accepting that can allow you to live more authentically. As you come to terms with your gender, you can experiment with gender expression. Also, use different terms and see which one feels most accurate to you.

    Supporting Someone’s Gender Identity

    A loved one whose gender doesn’t fit into a single category may confide to you that they are non-binary or that the identify with more than one gender. You can be a source of support for that person whose gender is fluid or fluctuation. You can do this by:

    • Respecting their name and pronoun usage
    • Encouraging them to find support online or in the community
    • Using inclusive language
    • Remembering non-binary identities
