well for me, i didn't know ftm's existed. the idea of ever being a man was just not a possibility to me.
it wasn't till about a year ago when i even stumbled across the term and it took me some time to accept i could do this and now that i've come to terms with how i am im rather fine about being trans and persuing transition.
i suppose I never geled with my body, as a kid i was fine with it, my genitalia don't bother me it was always the secondary characteristics. once puberty hit i did everything in my power to hide my boobs. they aren't big which is why i wasn't SUPER dysphoric about them, i'm a A, but just knowing they were there made me dress in baggy clothing and do everything i could to deny there existance. i didn't even know i was doing it subconsiously till i noticed i was going through extra effort to hide them.
it wasn't till later when i tried to picture my future, being told i wanted to be a mother and settle down i couldn't picture it for me. i wanted kids but i would never want to be pregnant or fill the mother role, i wanted to be the father. my job i always pictured myself in a suit i didn't like seeing a woman in a skirt or dressed in formal clothing that wasn't a suit and that bothered me. and really it wasn't until last year i realized there was another step my subconsious was telling me would happen. that this being female was temporary, there was another step for me to become a man and i never realized what that step was.
I became dysphoric once i started working out to gain muscle mass. I wanted big muscles. the biceps teh abs the pecs, the back all of it. I was using p90x which really helped me pack on muscle but my father was very insistent i stop upping the weights when i got comfortable with 25lb dumbells, saying it's doesn't look good when a woman has big muscles and i shouldn't keep trying to get bigger. this upset me deeply, i ignored his advice but i soon realized my muscle growth didn't resemble males at all. it was lean and hardly defined and i was working hard, i did the whole program why didn't i get the results like the men. and then I really realized, this is the wrong body, i would never be a man. it wouldn't happen magically through diet and exercise it was in my DNA. if I wanted muscles and to look like a man I had to change myself on my own terms.
that summer was hard because I was trying to figure out why i couldn't just magically be a man, i was looking for any excuse that made me closer to masculinity. my PCOS i realized upped my testosterone lvels a bit so i stopped taking my birthcontrol bpills and it helped, my boobns shrunk a little, less tender. i cut off my hair, which was liberating, i felt fantastic. and i realized teh more i brought myself closer to a masculine thought and appearance the better i felt about myself. when people said i looked manly (being 5'10" and broad shouldered for a girl it was easy for people in high school to say that of me) i took it as a compliment i never corrected them.
it was the summer my senior year i came across the possibility to transition. it seemed far fetched and risky to me. but the thought i wasn't male and never would be weighed so havily on me and i was so afraid to tell anyone. my father noticed ( i live with him, he's very open minded he doesn't care what i do) he saw i was being reclusive and epressed, i'd lash out sometimes and he finally just cornered me and asked what was wrong and i spilled and soon after i was seeing a therapist about it. the therapist asked the hard questions for me. and soon i came to terms with what i wanted and realized i only got this one life to change it. i can put it off or just get it over with and i've decided to just get it over with, there will never be an easy way to transition and i've just been coming out to people and i relaize everyones got some support for me that im around and all has been well, i didn't have anything to be scared of. I'm lucky in that regard.
tl;dr
I didn't know i was trans because the possibility didn't exist for me. once i found out it still took me some exploring but eventually i just came to terms with it. screw the world it's my life i gotta live it the way i want.
