Yes

You remember back to your childhood. Before your breasts grew your parents were much **** to you. They thought that if you could pass as a man then they could let you become a knight. That way you could go find a princess or any other respectable noblewoman to marry and produce a true heir to their throne, preferably one without something extra. They gave you books on survival skills and sword fighting. When your breasts blossomed to an impressive size, along with other feminising features developing like a thin waist and wide hips, they became disappointed, made you painfully hide your cock and removed the books.

However, you still remembered the basics. Taking the Silver Burch bark out of the tinderbox and gathering some to replace it. You use your makeshift knife to scrape the bark into flakes. You take place these on a larger piece of bark on the ground. you take the flint from the tinderbox and strike it. Sparks fly and you get a flame. You build it up with twigs, soon you add logs and have a fire. (this is real bushcraft you can use this in real life. I have simplified it for the story and so not to reveal all the steps, just be responsible, don't play with fire unless you are a dragon)

You have fire and use it to cook some food, It should also keep predators away. You put the tinderbox away and take out the bedroll. You find it hard to sleep, you are in uncomfortable man's clothing, sleeping with a dead man's stuff for the first time there is no roof over your head and no dragon guarding you. You are scared but you are free.
