Demigender

 is a nonbinary gender identity that involves feeling a partial, but not a full, connection to a particular gender identity or just to the concept of gender. This includes the partly female identity demigirl, and the partly male identity demiboy. There are other partial genders using the "demi-" prefix for the same reasons (e.g. demifluid, demiflux, etc.).
