Is it normal that i like to create sores on my tongue?
I have a habit of repeatedly biting the tip of my tongue to create a little white sore on it. When i eat chocolate is usuallywhen I get the urge to. It hurts but feels good to rub my sore over my teeth. I like to see how big of a bump on the tip of my tongue i can create. I don't bite it to the point where it bleeds, just enough to create a kanker sore type sore
