There can be an interesting attraction between a Te-dom and a Ti-Dom. My LII sister married an LSE, and I have been involved with two LSI. The attraction is between Te and Ti, because together it makes a single thinking whole, and the mind seems to like that a lot. It can be mistaken for a sexual attraction, especially if the two people have compatible erotic attitudes. Of course, there are some other problems in these relationships. The Te-dom is seeking Fi, and the Ti-dom is seeking Fe, and both feel that something is missing.
No kidding, regarding the "hard to get acquainted with" statement. Upon first meeting, you say Hi! and they say No No No NO and they start watching you from a distance. Since their ability to predict the future is not great, they have to accumulate information as it arrives in order to make a decision. They compare what they see right now to what they remember from the past, and if their past is full of bad behaviors, they are comparing your actions to those. There is very little ability there to choose between future possibilities. Therefore, any advancement in the relationship happens at the ESI's pace, as she establishes the fact that she can trust you (or not), based on your actions. Eventually, she is either interested or she isn't, and there isn't a lot you can do about it. So, you just have to hang around and be yourself and wait and see what they decide.
This is probably a good thing, now that I think about it, but it is probably why LIE's have a minor reputation for being easily friendly with women. We don't want to grow old waiting for a No decision.
Yeah, that happens. Nice, isn't it?
Eventually, it becomes addicting. I was visiting a lunch counter once a week for a couple years where an ESI-Fi worked. At one point I realized that I cared more about the time I spent there than I did about my work, or lunch, or any other thing. If I missed a week, it affected my mood in a very bad way, which is how I discovered the problems of being dualized, and then losing that.
That's really why I became interested in Socionics. It seems to be able to predict very, very well what I see in real life.
No, I have never seen an ESI in business school. You are going to have to visit the Nursing school or the Art School for that.
Don't delay in finding one. They tend to marry the wrong guy (not you) early, and their loyalty causes them to stick with the guy, no matter how bad it is, so they are all pretty much out of the pool by age 30.
Edit: Since discovering that you are female, my advice for finding an ESI is a bit different.
I'm going to guess that you lean more toward the Te-subtype, since they tend more to go into engineering, and the Ni-subtypes tend more to go into finance.
If you are Te-subtype, then you will probably be happier with an ESI-Fi. If you are an LIE-Ni, you will probably be happier with an ESI-Se. This is not carved in stone, though, and your individual tastes may vary, and a lot of other factors come into play.
Male ESI-Se types tend to appear at sports events with friends. I have seen them working in jobs that require some physicality and involves the outdoors, like mechanic, trouble-shooter, astrophysicist.
The only male ESI-Fi I have ever met is extremely smart and works for a University and he never goes anywhere. At all. If he is not at work, he is at home. Good luck with that.
So, keep your eyes open at uni.
