I wouldn't say I possess a natural (or otherwise) affinity for the type or that I do so because it is low on the totem pole. Rather, I identify as it and accept it as is. (Because it is what I am.) Hence, my mention of not making it out to be conventionally beautiful or anything. It's a handy summary within the framework of my journey, a symbol. Though one that could be replaced with anything so long as the important part, the meaning remained. But of itself, I regard it neutrally. My apologies if my description of what it personally means to me made it seem that way.
As for my functions, I do believe I lead with Si in that I immediately internalize information/stimuli though I don't think this was obvious to myself at first because of how archaically I organize these things and how overburdened with subjectivity the process is for me. It almost seems as if the stimuli is forgone completely because I create weird extremely subjective impressions of it in my mind. In other words, I am incredibly subjective and see only the shadows of the flames on the cave wall. I think Si as per the popular conception is imbued with a Te empiricist flavor, hence that entire thing I've noticed about ISJ's being percieved as needing details and pieces in order to construct the whole. The rationalist flavor of Ti provides more fluidity and room for heuristics. I percieve that I create modular structures that I can easily use to skip over the minutae when the impressions contain similar pieces. Which is to say, that the atomistic building of the whole is what I have mostly seen from Te aux and doms, not Si doms or auxes. The only time I see it from Fe-Ti is when they are a 6 and therefore have security attachments to knowledge so, naturally gravitate toward more limited epistemic relationships via empiricism in order to ensure and have a way to confirm. But I don't think I am a 6. Thus, I can see the manner in which I connect things, a manner arcane but not abstract. If I took proper time and effort, all of my impressions could be unpacked like Russian dolls, because the shadows belong to the flames and did not come from anywhere but the world of the concrete. Though they are not the object themselves like Se, that is clear. This metaphor, in its original context, makes Si out negatively but out of it's context as I am presented it now it just illustrates my conception of it lol.
My making decisions with Fe was admittedly more obvious when I was younger and my Ti bled into/balanced it less (I have gained the ability of critical thinking since I was a teenager). But when I was younger, I would always look outward for the "right" answer or action from the objective then pursue it agressively, unquestionably, and fall back upon it when came time to defend myself. I believed there was a correct reality and way to be. I was often typed as a cp6 because I would react so strongly to external forces/pressures. I was not one step removed from them the way Fi doms and auxes are. In reality I was reacting to the lack of congruence (and not from internal values of themselves), which freaked me out as both 9 and Fe need it. This can still be seen to some extent in how meddlesome I can be, even when I appear to be passive sometimes I am in reality too sensitive to congurence/incongruence with the external to be truly passive. Fi is commonly associated with that sort of thing because Fe is percieved as only taking place in congruence. But Fe is really both sides of the coin directly. Fi is only secondarily concerned with that dichotomy, it's not directly concerned with it. That is, what I experience is my values as external and interacting/clashing with the objective structure of value thus demanding a reaction from me. Either convince/force congruence or give in (which can either be rebellion or alignment in reaction to the external but it's not trying to get people to agree with me).
Ti is my relief function, the one I go toward in times of great pain and distress. During the darkest period of my life (20- 22), I seemed to be incredibly detached and obsessed with subsuming everything to my framework (someone even told me "not everything has to make sense") because I was in such a stygian state that I had to detach from the correct narrative I no longer fit into and found relief only in destablizing everything I took for certain once a la the objective structures of Fe. I also looked the least Fe during this time because value judgements were subourdianted completely and instead I only picked everything apart. It looked almost like a Si-Ti loop in that all was information gathering, dismantaling, and integration into my own understanding of things.
My inferior Ne has a very disintegration to 6 flavor in that I create these very paranoid narratives for people with many branching possibilities of duplicity and ulterior motivations that I believe whole heartedly enough to act on them. It's not dismillar to the classic "1,000 worst case scenerios" portrait painted of inferior Ne imo. When I am in this mode I am making up possibilities that may not exist and if one doesn't fit, I have more.
