Thank you for your words of wisdom. Intrusive gags are usually what we use and what I have experience with. She has TMJ so most ball gags are too much for her. We have found a bit gag that she finds "comfy" wearing and it works well enough for my needs too. I have drooled before while using a bit but she never has yet. I was just wondering if there was a way to "make" her loose control of that otherwise not thought of bodily function. From my experience it just helps with that submissive feeling of having no control when that happens and I would like for her to have that experience...
