Curious as to what you mean by "acting them out"?

If your therapist is psychodynamic, she'll likely welcome the discussion. Especially if psychoanalytic. You could explore this and learn a lot about yourself.

Iv'e experienced this with 2 therapists and talked about it, it was fine. Mine wasn't that 'heavy' in terms of taking up all the therapy space or consistently present, although it had spikes of great intensity at times.

Not sure what you mean by erotic-loving vs sexual but am assuming you mean sexual. My therapist is psychoanalytic, and he said he talks about sex with clients every week of his life. Could be problematic with a non-psychodynamic therapist, who might not feel comfortable with the whole thing, as common as it is. In that case, it might be better to find someone else to work this through as this would likely come up again with another therapist.

Why do you have such a strong need to tell her?
