Now, I’m completely aware that what I’m about to reveal is beyond normal, but I don’t mind sharing.
I’m addicted to brush the middle of the back of my tongue when I’m brushing my teeth. I know, I know. It’s crazy. I can’t help it, though.
I can say that I do have control over it. I’ve never and don’t think I’ll ever do it to the point of bruising or becoming raw.
My sincere apologies if I made anyone feel uneasy or grossed out with my answer. Sorry guys.

It is okay. Thanks for your comment Latasha.
