Transmasculine is a term used to describe those who were assigned female at birth, but identify as more male than female. Transmasculine is often used as a catch-all term for all people assigned female at birth who identify as masculine of center, including trans men, but the adoption of the term as an identity is a matter of personal preference. Those who identify as transmasculine, as opposed to simply as FTM or a man, trans or otherwise, often place themselves masculine of center- that is, they identify more closely with maleness than femaleness, and generally desire a physical appearance that reflects this identification, but do not identify as wholly male or as a man. This identity is similar to that of a demiguy in that demiguys often identify with maleness or masculinity, but only partially. It should be noted that transmasculine is not a descriptor of gender expression but of identity. Transmasculine people do not necessarily have to be stereotypically masculine in their interests or even presentation.
