One of my friends is a transgender man who loves to wear dresses, and regularly does professional photo shoots in full girl mode. He identifies as male and is accepted as male by a lot of people, but just still likes being what society considers "girly". Consider that the gender norms we have as a society are pretty arbitrary. We could be living in a world where high heels, makeup, and fancy wigs are all "guy things" - the world was actually like that not that long ago. Maybe from the ridged perspective of a society with arbitrary gender norms what you like seems confusing, but in a more objective sense, it's totally fine.
I'm transitioning from male to female. I have always had a fountain of girliness inside of me, waiting to be expressed. However, that's not why I went on HRT. I never allowed myself to go on HRT for that reason. I went on HRT because when I looked at my body in the mirror, I expected to see female features. I went on hormones only so that I could be happier with my body, not so I could give myself permission to be "feminine". I don't feel that one's sex should define how they express themselves.
Basically what I'm saying is: if you feel more comfortable being physically masculine but still like to wear girly things, I see nothing wrong with that. To me, the two are totally separate things.
