OMG! Wow, thank you so much. I have never known about oral fixation, but it makes so much sense, and it explains so much, so much.
Here are some examples
I keep a cherry stone in my mouth for hours, playing with it.
When I cut of tags of new clothes, I'll put the plastic thing in my mouth and play with it for a long time
I chew on headphones cables
I put everything in my mouth. I don't suck on candy, chew it. I chew soft candy, hard candy. There has to be something going on other than sucking. (it sounds so pervy lol)
I most definitely need to find other solutions to this But just knowing there is a name for it, that it actually is something.
