Anecdotally, and YMMV, but here's a mask-wearing observation: I don't seem to touch my face when I am wearing my mask. When I pull my mask down below my chin or remove it because I'm in my car by myself or at home, I instinctively do so by pulling the ear loops down. On the rare occasion I adjust the mask, I instinctively pinch the fabric, and then I wash or sanitize my hands. But I don't think I touch my actual face while wearing my mask, it'd even be kind of hard to... I mean, I'd have to go out of my way to try to touch my face.
