Assigned-Female-at-Birth Trans Masculine and Non-Binary Individuals Differ in Their Body Satisfaction and Desire for Gender Affirming Treatments.

Many non-binary individuals physically affirm their gender, but the binary/non-binary component of gender identity is rarely reported, and when it is, assigned-male- and assigned-female-at-birth individuals are often grouped together. We compared the experience of assigned-female-at-birth trans masculine and non-binary individuals via an anonymous online survey and found that patterns of overall body satisfaction and strength of intention to modify the body support the idea that the lower engagement in physical affirmation by non-binary individuals reflects less need to undergo body modifications. Trans masculine and non-binary participants who had had at least one gender affirming treatment (GAT) mostly identified as trans and expressed a similar ranking of GAT preferences. In contrast, non-physically affirmed cohorts differed in strength of intention to modify their body, desired GAT and the proportion who identified as trans, with more than a third of non-physically affirmed non-binary individuals not wanting any GAT and a third wanting GAT without testosterone. Several participants who did not want testosterone used female-based identifiers suggesting that some non-binary individuals use GAT to defeminize rather than masculinize their bodies. Individuals' orientation to the binary/non-binary and trans/non-trans dimensions of identity appears connected to their strength of motivation to physically affirm and their preferred outcomes but there is ambiguity in the usage of the terms. We need to explore what these terms mean to a given individual if we are to support them as they make decisions about whether and how to modify their body to affirm their gender.
