I'm NB but I've been on hormones for almost 2 years and have definitely changed a lot while working for my current company. I've been with the company from when it was a 15 person startup to being a 200 person entrenched behemoth, and it's pretty much been a great experience all the way. Granted, almost no-one uses my pronouns(Maybe 2 or 3 people in the company), however they are listed in my Slack profile, I have only ever verbally told my team them a single time, and I haven't pushed since then. The more important thing to me is that I'm seen as a human being, which I feel like I am. My co-workers for sure think I'm weird(for many reasons), but they also accept me and appreciate my weirdness, even celebrating it in some cases.
I think it's as good as can be expected. Just the fact that the company loosely encourages employees to list pronouns in their Slack profile is a big win for me.
It's an awesome feeling to come to accept! I know many trans individuals who started off going hard binary trans, and then settling on something more in the genderfluid or nonbinary spectrum. I think it feels more right for some people to go full binary trans in the beginning in situations in which they have a part of themselves that has been heavily repressed by society. After they've "got it out of their system" so to speak, some people realize that they're actually not always one or the other gender.
It's an experience that some relate to and some don't. Congratulations on coming to a deeper understanding of yourself! <3
