I often question my j/p and my n/s, I'm positive I'm not an extrovert or a thinker. My scores were vary close but I think I fall more along the lines of and INFJ then anything else. So to answer your question, yes I do.
I'm not sure. Fe comes pretty naturally to me both online and offline, I feel it's more developed than Fi, because (as much as I hate to admit it) my morals aren't set in stone. It actually causes me a lot of guilt and is the reason for some of the threads I start here. What does strong Te look like?
It's possible I'm an INTP with developed Fe, but I think it's also possible I'm an INFJ, since INFJs also use Ti and Fe predominantly. Then again, contrasted against some of the INFJs here, I seem pretty different... so perhaps not. (But then again, INFJs as a collective themselves seem quite diverse, so I could just be on one extreme end of the INFJ spectrum. Haha
What's your reasoning behind not thinking you're an INFJ? I would've pegged you as one from your posts here =)
