How do I got about having my family use my preferred name and pronouns

So i live with my aunt and gma and im about five months on T so I don’t look or sound like a female i didnt really before T. It didn’t bother me as much before especially when I wasn’t on T but now that I am it is kinda bothering me being I don’t look like a female and she uses female pronouns and all. I just kinda don’t know how to really address the situation. Again it’s not bothering me to the point i’m upset about it but when i’m being addressed to someone else it just feels very weird you know. I know i just need to speak up but im kinda nervous 😅. Any advice is good advice guys. And just so you guys know my aunt is very supportive i actually moved out of my parents house because they weren’t to come live with her and my gma so it’s not that she doesn’t care but she’s trying, i think she mostly just forgets and it slips her mind as she’s speaking and that’s ok she’s been around me pretty much my whole life up until my teens. Anyways i know im just yapping at this point but yea any advice helps guys much love !!
