Your nervousness, shyness, and lack of friends during adolescence was probably due to introversion, not necessarily lack of F. I think you are an F because your passions seem so value-driven, and your interests lie in subjective subjects which cannot be clearly verified: languages, history, etc. That's not Te. Te would be more interested in things that could be proven. We could say that it's possibly Ti, though, especially since you were academically competitive. However, your need for structure and love of planning points to a J temperament. Your value judgements of your peers, that you hated promiscuous people but had great understanding for people who "needed to talk" strikes me also as an F trait, not a T trait.
I can't necessarily make a case for you being an Ni dom, per se, but everything about you screams INFJ to me. From what I understand, a person can rely on their primary and tertiary functions without developing their auxillary as much until later, which potentially could make you an Ni/Ti driven INFJ. But I think you had much more development of F than you think you did during your adolescence, which is why everything in your world was so value and passion driven, even if you weren't especially social.
EDIT: Also, your whole attitude toward church growing up - you wanted people to know "how it went" and had no patience for people who did not know the hymns - TOTALLY SCREAMS Fe to me, and it screams the sort of Fe expressed in a J temperament.
I do not get the more objective air of a T from your post, or any of your other posts I've read on here.
I'm not sure how you got T or ENFP, honestly. As an ENFP I was never particularly a fan of overly-structured environments, and even though I definitely have some of the introverted extrovert qualities of needing time to recharge, I had a theatrics streak all through my childhood and young adulthood, I was always on stage drawing attention to myself. And while in high school I wasn't popular with the jocks and cheerleaders, I was extremely social and open to more artistic/intellectual types, and enjoyed a sort of popularity my junior and senior years because I was so friendly.
The only other thing I could see you as is an INFP, seriously.
