In my own case I call both cis & trans women "guys" or "dudes" under specific male dominated contexts. Like during playing video games & pen and paper gaming.
This has always been fine except for recently there is a hiccup. My cousin has semi-recently begun transitioning, so whenever she's playing video games with me on my discord I kind of can't help but slow myself down (or end up correcting myself) when referring to her which I wouldn't do for a cis woman... Thus far they have not noted this as treatment differing what I might do for a cis woman because admittedly the cis women on my discord never jump in to play Battlefield or Killing Floor 1/2 anyways but it still makes me wonder if I'm helping or hurting the situation.
