Hey Arch,
I feel for what you're going through with your therapist referring to your past self as a "little girl," especially after you've already expressed how much that hurts.
Since you mentioned he's not queer or trained in gender identity issues, I wanted to offer a few thoughts on what might be going on, particularly in the context of inner child work and different therapeutic styles.
It's possible that this is part of an intentional "inner child" technique, but that doesn't make it okay without your consent.
It could also be unconscious bias, or even the therapist subconsciously seeking validation of their own framework.
Another possibility is that it's a misguided "therapeutic confrontation," where they're trying to provoke a reaction to surface unresolved emotions.
But the truth is, we won't know for sure unless they explain, and they shouldn't be using these kinds of tactics without discussing it with you first.
If you feel up to it, you might consider saying:
"You've used the phrase 'little girl' more than once, even though I've said it hurts."
And then asking directly:
"Is that part of a therapeutic method you're using? If so, I'd like to talk openly about why, and also be clear that, for me, it's not helping."
As for your original question: "Do you call your childhood self a boy, a girl, or something else?"
For me, it was both: a boy and a girl. That's what feels most true when I look back.
I hope this helps, and I'm wishing you clarity and strength for your next session.
Take care,
~ Lilis 💞🌷
