I'm pre-T and I mostly see myself as male, even when looking into the mirror. I came a lot more comfortable with my body once I knew what was wrong with it, and what I didn't like. The only reason I can think of that was that I understood that I was male, and can focus on the more masculine parts of it instead of trying to work out why I felt fat etc. My perception of my body has shifted since understanding that I was male because I'm projecting the male image on top of it.
However, I don't use full body mirrors when I'm not clothed, and being short has an advantage for me now, because in the bathroom mirror I can only see my shoulders and head, which are my most masculine parts. When I was on holiday and there was a much lower mirror (it came right down to the sink) I was extremely dysphoric the whole time, I had no binder, and I could see my chest and curves in all their glory.
Photoshopping a picture of me topless into how it should be made me dysphoric as well, because I'd never really realised how curvy I actually am, but it gives me a goal to work towards, and I force myself to see that when I'm in the mirror instead. Understanding my body issues and forcing myself to focus on the parts I like, mostly my shoulders, makes me feel a lot better. And I'm no longer expecting to see, or trying to see, a female there.
