Transmasculine

Transmasculine, sometimes abbreviated to transmasc, is an umbrella term that refers to those who were assigned female at birth, and whose gender is predominantly masculine and/or who express themselves in a predominantly masculine way. Transmasculine people feel a connection with masculinity, but do not always identify as male. Transmasculine people can include, but are not limited to: trans men, demiboys, multigender people, genderfluid people and nonbinary people, as long as they identify more with masculinity than anything else. Transfeminine is the feminine equivalent of transmasculine.
