probably would be the same size height wise.
I'm 5'4 short for a dude, but it fits me. I feel like maybe being a bit taller couldn't hurt for defensive reasons, but at the same time I think its a slight bit paranoid to think like that.
Build would probably stay about the same too, although I would have a good bit more muscle definition and that slight hint of girly hip curve would go away [which it probably will within the next few months on T just going on a year now]
I think the really only big difference would be the addition of a working phallus ect of proportionate size.
