hehehe our little princess is being devoured by a very handsome wolf

I think you mean our prince. He isn't female and shouldn't be addressed as such, it's insulting. No man wants to be called such or compared to a woman.

and yet, there are Yaoi out there with the title of "The Princess is Mine!"

And some where they cross dress.

I've even seen yaoi's where the uke was excited to be carried "as a princess".
