I have, I will if circumstances demand it.
I'm not especially tough but I know how to roll with punches well, and seem to have good luck with intercepting punches with an elbow or my forehead. I can usually kinda stick to opponents and gradually force them into letting me isolate a limb or get them off-balance and unable to strike effectively.
I used to deal with a lot of physical bullying, including getting jumped by groups of people. I've gotten beaten up plenty, but that gradually taught me how to make trying to beat me up as frustrating as possible. I make it so the other party can't effectively attack, then work to put them in a position they can't effectively defend themselves either, or at the very least, where I can do something they can't resist (like small joint manipulation or cutting near their eye with my thumbnail).
If someone wants a fight with me, they'll get it. It won't be satisfying or flatter either of us, but they'll get it.
