Trans masculine is an umbrella term used to describe individuals who were assigned female at birth but identify and/or express themselves in a more masculine or male-aligned way. This term encompasses a diverse range of gender identities and expressions, including but not limited to transgender men, non-binary individuals who lean towards masculinity, genderqueer individuals, and others. It’s important to note that not all individuals assigned female at birth who identify with masculinity identify as trans masculine, as gender identity is deeply personal and varies from person to person.
