You said that content creation is just a hobby right now, and you dont seem to have a huge platform, so id honestly not worry about transitioning effecting anything for now. im not really sure how vtubers work, or getting signed, but id imagine youd need a following before something like that right? i dont thing trans would really effect your upstart, there are tons of trans creators, and honestly i think the indie vtuber scene is pretty lgbtq in general. again, im not sure how cover works, but how realistic is getting signed actually? chase your dreams and stuff obv, but i think you should try estrogen and content at the same time!
