Its much netter for me to move away from gender and/or sex when exsplaining to my dad about trans related stuff.
likes and dislikes people can relate to.
eg, when arguing with my dad, i dont say im getting lazer because stubble is a man thing, i simply say, im getting lazer because of how having to shave makes me feel. i say i hate it, and if my face isnt smooth i keep going with more and more pressure and frustration and it cuts me everywear.
I esplain how shadow makes me feel. and how when i can notice it, i feel like digging my fingers deep into my skin and tearing off the complete bottom of my facial area. and that all the cuts i gain as a result of shaving amounts to the same thing.
I say, i want my hair this way because this IS how i want my hair. regardless of wether it boyish or girlish, its not about getting girl hair or boy hair, its about having the freedom to have my hair how I want it for a change, instead of how other people want me to have it.
the same with clothes.
Now if the end result of all this stuff ends up with my presenting as somthing more OR less feminine then before, that is where I as a person, an individual, being themselves, who they are, IS supposed to look.
Now if you cant get your head around how i feel at the moment (incert specific person here) why dont you, walk around with (enter complete asthetic contrast here) and see if you dont feel somthing like i do now?
And to argume my likes and dislikes I ask them things they like and then say, no you dont like all that stuff, and say you like all this other random stuff.
Ofcouse they disagree with me thats the point, it lets me say, you didnt like me telling you what you like and dislike did you? and i dont like being told what i like and dislike either

All I want is, to be able to pic and choose my own clothes like everybody ells, to have my hair how i want it like everybody ells, to do and not do activities i want and dont want to do. what is wrong with that.
usuall responce, boys this, girls that, yada, yada. so I SAY i told you its not about that. Its about ME a person that just wants the same freedoms as everybody ells.
