He's never been allowed to fight monsters; the minotaur was the very first beast he slayed and he had no idea what it was.
Before that he had some basic training and then he kept trying to improve his parry skill with (wooden?) swords dangling from trees.

Apparently, but I don't understand how.
It's fine though, thinking back on it, I've figured it out; those badass scars are from rescuing pets.
