Xenine

Xenine is the xenic/xenogender counterpart to feminine, masculine, and similar terms. The noun form is xeninity. Genders which are xenine in nature are referred to as xingenders. Somebody who is xenine typically doesn't have a strong sense of their gender, but rather vague ideas and feelings.

Xenine does not fit within the western binary of gender, and does not have the same roles/stereotypes that masculine and feminine are associated with.
