There’s no formal process you have to go through that means you can use different pronouns. If you want to change your pronouns, nothing is stopping you. Several websites and forums offer spaces where you can try out different pronouns. You can also write to yourself using new pronouns to see what feels best.You might find that more than one set of pronouns feels good to you, with or without a preference for one. (For example, both they/he and they/she are two common combinations.) Pronouns can also be fluid across settings and over time. You might only use singular they or neopronouns in places you feel safe and rely on a binary pronoun in new and unsafe situations, such as at work or school. Once you’ve decided you want to use different pronouns, you can ease into telling people or coming out. This can look however you want to, from a grand social media post or slowly telling people you interact with in person. The Trevor Project has an excellent guide on coming out as transgender or nonbinary. GLSEN uses first-person stories from transgender and nonbinary youth with tips and tricks to help you feel most at home in yourself and come out to others.
