It took me awhile to get used to it, but like Hyacinth I've always had trouble (especially in childhood) mixing up even cispeople's pronouns. And I would get called "he" a lot before transition until I learned to pitch my voice higher and do all the other right girl cues, and I dressed boyish, so I had a lifetime of people using male pronouns at first glance and then profusely apologizing. Or people on the phone thinking I was a teenaged boy. So then in transition that kept happening for awhile, and then it reversed for awhile, where someone would say "she" and then apologize (though lol not as profusely), and it all just felt interchangeable. I didn't start getting used to hearing for-sure male pronouns until I had been consistently read as male for a long time.
Now I think I'm pretty used to it, but sometimes I falsely think I hear "she" in reference to me, sorta like how you think your phone is vibrating when it's not. Old habits die hard. It doesn't help that there are a few people in my life who are not accepting of my transition and won't stop misgendering me, but luckily those people are in the minority.
It's nice to take hearing the right pronouns for granted, but I hope I always remember to notice occasionally how good it makes me feel.
