Boyflux

Boyflux, also known as manflux, is a gender identity that describes someone who is a man at least some of the time, but their feeling of manhood fluctuates between different intensities. At 0% intensity, they would be agender, and at 100% intensity, they would be fully man/boy.

The Flag
The boyflux flag has varying shades of blue which represent the fluctuating intensity of the male identity, and a green stripe in the middle to represent agender or a lack of gender.

Terminology
Tumblr user kitsuneshay coined the terms girlflux and boyflux to describe their gender identity in 2015.
