So spiritboy spiritgirl or spirit whatever suffix you like is a type of transgender where you are the suffix of the gender in spirit, just not physically, it's the same as being someone of that gender the only difference being that you aren't that physically and also very likely don't wish to be. So like being trans but your identity is that you aren't trans physically, just solely in spirit and everything else.
The flag for spirit(gender) is light grey, thin darker grey, the colour used to represent your gender, thin darker grey, light grey.
Here's what that looks like for the spiritboy flag :)
Another gender I am coining here is called cassphysical or cassphys, it's like being cassgender or cassgenital but literally nothing about your physical gender makes any changes to what you identify as being what you feel your gender is, it's like the physical gender/hormones/ect is just kinda there and doesn't have any effect on what your gender is, this could also apply to being a cisgender person who still identifies with the gender they were assigned at birth but their physicality has no effect on what that gender is to them and it comes from solely their identity, not their physicality. Cassphysical based on my experiences is quite euphoric, like that's just how it is my physicality is just there and I'm chill about it, it can also carry over to non-sexual relationships where your partner also doesn't care what you are physically and just about your identity because that's not what they value from relationships. The cassphysical flag is purple, sand, slate, black, and yellow.
This is how that looks :)
Both of these were coined based on personal experiences and are free for use of anyone with similar experiences :D
peace y'all <3
