You dont have to ask permission to start
You can feel it in you, that electric fuzz when you think about those pronouns, that label, those clothes. Something is stirring but you dont feel permitted to commit. You turn to others for valudation, asking is it okay if i do this? Do i seem right for this? Do you think i am man enough to be a man? And its okay, i dont blame you, i see the damage that decades of transphobia and transmedicalism has done around you to foster this enviroment.
But i wish i could take your hands and tell you to just dive in, dont ask, dont wait for permission. The waters lovely, its here for you and its all for you. Jump in as soon as you feel the urge to ask someone else if you can. Are you scared you'll be wrong? Thats okay, better to try and be wrong then to go on never having tried. This is yours to explore, this is one of the most personal and individual acts you can take; exploring your identity is something you and you alone should take the reigns on, you dont need permission.
Dont delay the joy and freedom, just jump in. Nobody else need tell you to do it, there is no real marker for 'seeming valid enough' or 'sounding trans enough', you dont need to let others dictate this part of your life; because they will try, so many people will try to control this part of your life and i am so very sorry about the strife that causes. But the one part of it they cant control is you trying it out, changing pronouns in friend groups and names on social media profiles, reaching out to others online and declaring yourself something new. That is all yours my friend, take it in your hands and do not ask permission. I love you, bloom brightly.
