@Headstorm a few more thoughts now I've gone through the thread. I worked as a middle manager in the Information Systems Dept of a large Pharma for several decades - I ran a variety of teams supporting our research scientists. I came across mbti in a amagement course over 20 years ago and emerged from the test on a dead tie INTP/J. The trouble is INFJs are chameleons and take on the flavour of the company they keep if its "magnetic force" is strong enough - and INTP/J was definitely well aligned with our corporate culture among the people I had most contact with. This is almost certainly confusing you in the same way and it isn't just on the tests - you probably identify with T closely when you read the text book descriptions too. There are several INFJ people in the forum who have very strong tertiary Ti and this can carry us a very long way in thinking it is secondary or primary. I wasn't comfortable originally about identifying with Fe, because it has been so sterotyped that I think it is presented in ways Jung would have disagreed with strongly. In particular, this stereotyping makes men hesitant in identifying with it. One of the reasons I joined the Forum earlier this year was to conciously explore using Fe in a "safe" environment, and I haven't looked back - it just felt so natural once I got used to it, and takes far less of my energy that the other ways I was dealing with the outside world. The interaction between Ni/Fe/Ti (and Se, glorious Se too) just seems to fit me like a glove - wish I'd known it 40 years ago *sigh*.
Anyway - an option for you is to try out consciously using Fe and Te within the forum and see how they fit. It's a pretty tolerant place as long as you don't explore the deepest darkest reaches
