In your words being selfish is your only criteria of narcissism. But that's far from the truth. We are not all narcissist and you don't seem like one to me.
I have read a couple of your stories, and your voice isn't as intimidating as you think. I don't know you in person but I've seen too many narcissists to a point I can easily spot one.
You are not even arrogant, which is very common with narcissists. You might be controlling and selfish but far from being a narcissist.
