People use “genderqueer” to describe a gender identity that is fluid, changing, or exists betweeen the binary categories of man and woman. While it’s similar to nonbinary, it’s not exactly the same. A “queer” gender may fall outside of, fall in between, or fluctuate among the binary gender categories of man and woman. People who are genderqueer often experience their gender as fluid, meaning it can shift and change at any given time. Genderqueer can also describe a position of questioning one’s gender identity during a particular period or in an ongoing way. source - https://www.healthline.com/health/transgender/genderqueer
