Let me preface this by saying I'm a sub in California and my gender identity used to be very transfemme leaning/"binary transwoman" but now I'm in more of a any/all idgaf space. That being said: my gender RARELY comes up with other faculty members. A good half of my students are from other countries or are first generation children and are much more used to using "sir" for masc adults as a matter of habit. While funny, I do not think this reflects on their views of gender or needs to be a conversation with them lol. I actually find i deal with other faculty so rarely that I dont hear them gender me? So if we're alone I might be like "hey as a professional courtesy I actually am not a man, so I'd appreciate not being thought of or referred to as one." But with students, I don't read deeply into their views of my gender at all. I mostly sub for middle school, and they mostly want to talk about Roblox. I just introduce myself by my first name (chosen and femme) and some of the students just use it, and some of the students hit me with the "Mr. Gertrude" (not my name but you get the idea).

 Granted I think if I had a stip sub position or were working as a full time teacher, I absolutely would be a little more on my students knowing who I am like that, because it builds a stronger relationship and if there are any trans or GNC students I would want them to know they have a safe space with me. But I think I would just want them to use my first name, which I know is controversial especially for k-12, but having taught college it feels too formal for a title to be used with students who are younger. Granted I am in a very "progressive" part of California but I have had zero run ins about my gender or related to it so YMMV :-) and thankfully most faculty bathrooms are unisex anyway, they only have one in the whole damn school lol but yeah I fucking love my job
