i would've started sooner if I had accepted that i was trans. I feel so much more comfortable with myself now that i don't hide under the title of "butch lesbian" (i don't even like girls). I still have a lot of dysphoria, but i am so much more comfortable dressing/acting/etc as a guy. I had heard about trans people, but never really considered that i may be one. but when i think about it. I even wore an athletic cup playing hockey without considering myself FTM (i don't know how i managed to miss that signal). I have always dressed more masculine than femme (except in high school, when this one girl referred to me as 'it').
But when I finally came out to myself I was 19, I immediately started being who i want to be, not what society thinks i should.
