Oh man, I love having a Fe type of boyfriend. Though, I can't say his type with any accuracy as he seems to test borderline on all of the letters, I've given up on the notion that he's a T type because Fe seems to spill out of him. Most likely, he's an ISFJ, INFJ, or an ENFJ.
I like that he understands me and does the sort of things that I would also do to show my love. There's no question about feelings in the relationship like I've had with most T types I've dated (and Fi types, whom I could never understand). He's certainly a GUY, acts like a GUY, and takes on the more male role in the relationship. He just tends to take care of me more than other guys have in the past and be a bit more perceptive about my feelings. He also expresses how he feels rather easily.
As for the comment somewhere that a T/T or F/F relationship couldn't work... my current relationship is the EASIEST and quite possibly the most functional relationship I have ever been in. There is certainly a spark between us (hell, we're both givers ), despite the possibility of being the same type, because we're individuals and have different levels of I, E, N, S, etc. If we are the same type, I feel he takes on more of the I & F and I take on more of the N & J so we balance out. We also have different development of cognitive functions, I'm sure, and we've had different childhood experiences that have molded us. If he's an ISFJ, then our different functions keep the spark going, I guess.
