“Transgender people experience their transgender identity in a variety of ways and may become aware of their transgender identity at any age. Some can trace their transgender identities and feelings back to their earliest memories. They may have vague feelings of “not fitting in” with people of their assigned sex or specific wishes to be something other than their assigned sex. Others become aware of their transgender identities or begin to explore and experience gender-nonconforming attitudes and behaviors during adolescence or much later in life. Some embrace their transgender feelings, while others struggle with feelings of shame or confusion. Those who transition later in life may have struggled to fit in adequately as their assigned sex only to later face dissatisfaction with their lives. Some transgender people, transsexuals in particular, experience intense dissatisfaction with their sex assigned at birth, physical sex characteristics, or the gender role associated with that sex. These individuals often seek gender-affirming treatments.”
