@chaoswitch08 i know my experiance when coming out was feeling insane euphoria when it came to masc pronouns, and when people call me by my chosen name.
I also know it’s extremely stressful, cus you’re scared about who you feel comfortable sharing with and just summoning the confidence to say “hi my name is (chosen name)” is one of the most terrifying and confirming feelings in the world.
Also if your going to be writing will before he is able to get his hands on one of those magical binders (that i wish i had) i know one thing i did, (and still do) is wear multiple bra’s that are sometimes two small in order to make my chest look smaller. As well as wearing baggy clothes.
Last little bit of advice is try to censor the deadname if you can. (That was probably pretty obvious tho)
Hope that helped
