You know, I'm starting to think you're right.
I am Se PoLR and I am definitely aware of my Se. When I'm using it, when other people are using it. The PoLR function is in the mental ring. We tend to be more consciously aware of the usage of the functions in the mental ring.
For reference, mental ring functions are 1-4. Functions 5-8 are in the vital ring. They are more subconscious and tend to just 'do.' It's harder to verbalize our reasoning or the process of how we use the vital ring functions.
