@ the OP: Sometimes. It depends. I have best friends of all types (ENFP, INFP, INTJ, ESFP, ESTJ), and I relate to them all very very well, so it's not an issue of understanding. Generally I think I embrace new friendships and want to make them as close as possible, but I'm always afraid of offending the close friends I already have by trying to take on new friends, so I have to be careful. I'm already "fought over" enough as it is, so... I don't know. And yes, as Benedox said, we DO think about these things. I tend to focus on what other people will feel when I make my decisions (Fe dominant ).
I think it happens waaaaaaayyyyyy more frequently with friends of the opposite sex. I rarely have trouble with developing and maintaining healthy and emotionally-intimate female friendships. But with guys.... I don't know. I'm always antsy about sharing too much.
