I like your story. When I was a young girl I was called a “tomboy”. I had a horse and I rode Sugarfoot everywhere. I wore boys bluejeans because I don't think they even made blue jeans for girls back in the early 50’s, at least not where we shopped.
I remember thinking to myself that I was going to wear bluejeans my whole life and I didn't care what anyone else thought! I am 73 and I do still wear jeans but it's nothing unusual now for women to wear them, but I don't ride horses anymore.
Bless you. I'm sure there have always been girls who liked horses and sturdy boots (or mud on their feet), just like there have always been boys who liked singing and poetry and flowers.
No reason to abuse them --- surgically maim them, hormonally confuse them --- with this trans-sex trans-gender crap.
