Also, I'm wondering if an uber-introverted looper with no external functions could even possibly be an outer-directed social first, like you think I am. We actually focus our attention in similar areas, like how we each gather opinions from a bunch of people and try to harmonize them together, which could be Fe (and it would be very weird if I'm in a Ti-Ni loop yet have stronger Fe than Se).
You said how in your eyes I have no Se, but I think I may have a lot of an S function somewhere. I'm actually very athletic and used to be highly adept at soccer along with having a good eye for the beauty of nature or general observations of how anything works. I also like to have regular routines I follow without much deviation as far as my independent studies and general health goes along with some chores. Both of those things actually kind of relax me and allow my mind to drift off, so I guess I could be comfortable with either Se or Si.
Perhaps most importantly is how you mentioned my lack of Ne imagination. I think it actually speaks more for me being an Sx last. This is because you told me to imagine a bunch of silly sex scenarios, and if I have pretty much no Sx, then it follows that I wouldn't be inclined to imagine those sorts of things.
Thanks for your input by the way. I value your opinion quite highly.
