For the most part I haven't been conscious of much dysphoria, and it has mostly not been a (conscious?) motivation.
What makes it difficult for me to talk about any of this is that I feel like I've spent my life split into two people: the conscious me that deals with the demands of the world, and an inner me whose workings I mostly am unaware of. (I call it "DID lite.") I think this is because I grew up in an environment (home, school, etc.) where if I ever acted from my own impulse or from my own thinking, I was punished or shamed or ostracized or looked down on like the skunk at the garden party (usually more than one of these.) Nobody, absolutely nobody wanted to know anything about who or what I really was, nor to have to be aware of its existence. So I created the "outer me" that tried to behave and talk and think as I was expected to, but when I was safely alone I could live as the "inner me." But every now and then, I feel a strong impulse to move my life in a particular direction, and I call this my "inner oracle," which I assume comes from the "inner me." For instance, after a decade or so of hearing about trans women, and reading a blog post which seemed to describe me, I was seeing a therapist, and in the middle of the session, my "inner oracle" told me, quite to my surprise: "you're going to transition. Just thought you might like to know." I think a lot of feelings stay in the "inner me" and don't get felt by the "outer me."
So I don't remember having any particular gender dysphoria, but once I transitioned, I felt so much better (gender euphoria.) And as soon as I was living as a woman, it seemed obvious that I should sign up for SRS. I can't say I It took me 7 years to get there, mostly due to the messed up medical system we have in the US, but once I got to my hospital room after surgery and got to look at myself "down there," I just felt so much better about myself, even before they got the dressings off.
I had a lot of rational justifications for getting SRS, mainly that, like KathyLauren, I could see that the USA was headed towards rampant transphobia and the harder I could make it for the transphobes to identify me, the better. (That was also why I changed my birth certificate (once it was possible), even though I think it's stupid, but then, that's transphobia.)
I did have one experience of gender dysphoria: I was getting some sort of medical test which involved me getting X-rayed multiple times while I was wearing only the usual hospital gown, and my testicles kept being very visible, and I felt awful about it. That is why I got an orchiectomy, because I didn't need to wait 7 years for that.
So if you really want to know about my "priorities", you'll need to talk to the "inner me." Who isn't good at communicating with the outside world.
And if you ever figure out how to communicate with my "inner me," let me know how you did it. My therapist and I would love to know.
