Why do you have to meet any particular standard of what a Real Boy (tm) or a Real Trans Boy(tm) has to be?
There are any number of ways boys can be, so it follows that there are any number of ways for a trans boy to be.
For instance, meet C.J., over at
raisingmyrainbow.com . He's AMAB, and he makes it clear that he's a boy, not a trans girl. And he likes sparkly dresses, Monster High, princesses, dolls, and girl stuff in general. His friends are (mostly?) girls, and he's quite girly and proud of it, at least if he's not getting bullied too much at school for it. Oh, and he is obsessed with RuPaul's Drag Race (ugh!)
A girly boy is still a boy. As is a girly trans boy.
If you feel, in your heart of hearts, that you are really a boy, then you're a boy. (And if you want doctors to make your body more boy-like, then you're a (trans) boy who wants medical transition.)
The rest of the stuff doesn't matter.
You can have long hair and be a boy. You can be un-macho and be a boy. You can be nurturing and be a boy. You can wear cute dresses and be a boy (though you might have to do a little explaining to the more clue-deficient

)
You can be a boy any way you want to be.
EDIT:
Oh, and if you feel like you're a bit of both, or neither or whatever, then
that's who you are. And you can have whatever interests or be macho or un-macho or whatever, and it doesn't affect that, either.
The point is for you to be
you. (Not that that is at all easy, I admit.)
