Aha! This is something I know about. I transitioned 15 years ago, and I had my SRS 13 years ago.
I find that as time passes, I am more comfortable in my own skin, and I 'try' to pass less. What I mean is that I have become much more like most of my cis-female peers. I dress more like women of my age do now, I use much less makeup than I used to as well.
I never 'forget' that I am trans however, and I still worry about some things like my hair not being feminine enough, or my visible Adam's Apple. I still have to really work on my voice, because it still is not very good.
But on the whole, the things that cis-females have to put up with, or work on, like shaving your legs, or making sure your appearance is smart for work, or suffering sexism, all the things that might have once been new and hence exciting or interesting or challenging, are now run-of-the-mill, or a pain.
"Normal life" takes over, with all it's trials and tribulations, and transitioning and being trans kinda takes a back seat.
Partly that is good and to be expected, but I do sometimes miss the sense of wonder and discovery that I had when taking my first tentative steps out in the world as a woman. It really is an amazing experience, and not much else compares to it really.
I remember saying to my old boss: "I've had so much fun, I really ought to change sex more often!"
I still want to get married, and have a nice secure cosy relationship with my fella. I hope that will happen one day.
For myself, I get bored very easily, so I deliberately spice things up a bit every now and then. And every 7 years or so, I find I really have to make some changes to myself in order to feel alive and not stuck in a rut.
Just now is one of those times, and in the past few months I have revamped my writing and the way I walk, to be more feminine.
I applied for a new job today, just to challenge myself, even if I might still keep my current job.
I'm looking at some minor FFS, Adam's Apple removal, hairline improvement, brow ridge reduction.
Just stuff to change and work on.
I can't just stand still, but that's just me.
In short, yes you do move on, and life continues. You just now deal with it as the gender you actually are, both outside and inside.
