"How do you know you're ace if you haven't tried it yet?" Slight vent but mostly ????

TLDR : My therapist is being insane and is convinced I'm not ace because I haven't had sex yet — How do you deal with having to argue with people about your identity? and what do you even say to someone (that you trusted) when they refuse to be accepting?

Context : I've been seeing my new therapist for a couple of months now and only finally brought up the fact that I'm ace. This was in context to someone asking me out and me talking about how I don't know how to come out to them about being ace.

I thought this would just be a regular discussion, what I didn't expect was my therapist being like "?? you're ace? how do you know?" I told her that I just do, that I know myself and I don't feel sexual attraction, never have, don't know what that's like and that I just am. She (unfortunately) counters with "Have you been assaulted? do you think it's a trauma thing?" When I also say no and that I've never had sex and I'm happy keeping it that way forever, she kept insisting that I wouldn't know if I didn't try. I tried the well I don't need to eat poison to know I won't like it. She used this as a gotcha moment to be like oh you think sex is a bad thing.

Anyway, my back and forth with her went on for a lot longer than I would've liked, and I know realistically I should stop seeing this lady if she's going to fight a basic fact about my identity. HOWEVER I do want to try and educate her (a little) before I stop seeing her (which will probably be after the next session).
