The interboy flag.

Interboy, Interbro, Interguy, or Interman is an exclusive gender for intersex individuals who identify as men in a uniquely intersex-way. They may feel as though they are an altered form of a man, or they may just wish to embrace the intersex part of their identity, despite feeling little to no connection to it.

To be an interboy, one does not to have been assigned male at birth or be biologically close to male. Instead, they simply have to identify as a man in some shape or form, regardless of whether or not they have biological male characteristics.

If someone identifying as interboy has biological male traits, they may also identify as cisgender, however they do not have to if they feel cis does not match their experiences.

They may or may not be fluid or fluctuate between man-related identities, or (more specifically) intersex-related man identities.
