It's weird seeing your reflection for the first time when you're 25.
I mean, in a strictly literal sense I had seen my body in mirrors before countless times. But it took until I experimented with presenting as female—not doing drag but something deeper—to realize that I'd never really connected with that reflection. Intellectually I knew it was me, but emotionally/mentally I was disconnected from it. I struggled to picture myself in my head or visualize myself doing the things I wanted to do. I wasn't even aware that I had these problems until I started exploring being trans and realized that I could picture a girl who looked like me doing all these things.
I've never been, like, strongly dysphoric. Presenting as male never made me feel bad, it just made me feel nothing. But presenting as a girl? I felt amazing, like the world suddenly got more colorful and vibrant.
It's weird seeing your reflection for the first time when you're 25. It's weird realizing that you hadn't really been seeing it for all the time before then. But it's wonderful seeing it for the first time, and I'm glad I got to do that.
