Hmmm...interesting...
Well, as an ENFJ, I can say that I pick up on ISTP's displays of Fe..which I crave so deeply. It has charmed, and comforted me when I needed it the most...
There is such a vulnerable, and seemingly childish nature to it that really warms me..They are very attuned to my emotional state, and I can't really escape it.
If ever I become passive, sharp, blunt - they know how to regulate my emotions. And there is no way of getting around it. They just know. They know when I am "off." They know when I'm stressed. And without words, they are there for me. Be it a gentle squeeze of the hand, a nod, a look. They always pounce, and when they do, it's mainly physical, or a simple exchange of just a few of the most perfect, cryptic words that results in my sigh of relief.
Not to be sappy but, they pretty much heal me. Reaching out with that inferior Fe, connecting with mine. It's sweet. And..I really appreciate you ISTP's for it.
