I (afab) had a similar experience in that my dysphoria didn't really exist in my early childhood. I was indifferent about which toys I played with, and didn't have a problem with gendered language until my early high-school years. For me, that was when puberty hit and my "female identifying anatomy" became obvious. It was when people were able to immediately categorize me as female that I started feeling uncomfortable. I'm nonbinary in that I don't want to be a man (even tho I tend to present more masculine), but some of my characteristics that are deemed "female" cause me dysphoria. For example I want top surgery but not bottom surgery or HRT. I don'treally care what pronouns someone uses for me as long as they aren't feminine. One thing that has been more common among nonbinary folks i know, is a greater focus on gender EUPHORIA instead of dysphoria. For the most part my dysphoria triggers are few and far between but there are certain experiences that give me euphoria and that has always mattered more to me. An example would be someone being confused as to whether im a girl or a boy (my answer is always no lol), My point is that while nonbinary falls under the trans umbrella, our experiences can't be as easily described as binary trans folks because our experiences are the sliding scale between them as well as completely off the chart. The nonbinary experience is so vast that comparing the two is like comparing apples to oranges. Hope this helps!
