How to make a non-sexualized femboy OC?

So I'm gonna name him Xavier and he has a full story about his gender dysphoria. Basically, since he's my self-insert, his future self would probably be more comfortable with long hair and femboy clothes or whatever since he'd be on T for a while and pass, but I'm making his current self 16.

He lives with his transphobic family but he wants to look feminine in a "male way" and cut his hair to alleviate dysphoria and look more manly but he still wants to be feminine, if that makes sense.
