Demiboy (also known as demiguy, demiman, or demimale) is a gender in which one is partially, but not fully, a boy, man, or otherwise masculine. They may or may not identify as another gender in addition to being partially a boy. Demigender people may also identify as non-binary, and might use a form of gender neutral pronouns such as they/them, or a combination of neutral and masculine pronouns such as they/he. If a demiboy is not assigned male at birth they may also consider themselves transmasculine.
Demiboy may also be used by people assigned male at birth who feel little to no connection to masculinity, but usually do not experience a significant enough dissociation to create real physical discomfort or dysphoria.
The feminine equivalent to demiboy is demigirl, the non-binary equivalent is deminonbinary, and the neutral equivalent is demineutrois.
