I've been in therapy numerous times since my teens (I'm now early 40s). The first time transference for a T happened was with MC (though I also had some negative maternal transference for ex-T, who I started seeing 6 years ago, but I don't think that's what you're talking about). I did have some transference for a high school teacher though (of course didn't realize what it was at the time). And now I feel like I have some transference for current T, but nowhere near the intensity as for MC (at least not now, 6 months in).

So...no, I don't think it happens for every therapist.
