Hi everyone! Thanks for your replies.
The first meeting went well. She asked basic diagnostic questions. Very introductory. Asked for my gender, said "unsure." For preferred pronouns i said "I don't care. I've always used he/him, but she/her would be ok too, I like hearing or seeing that one when I'm online." That probably was a missed opportunity.
Then we went through most of my life (we stopped right at my high school graduation). She would stop and ask questions to delve into certain points in my life. And for the first time ever I told the story about how my parents had me switch schools because I came out on Myspace the summer before 8th grade. And it was interesting because it's a time that I want to forget and having to talk about it is really making me think (since I tend to just overlook the uncomfortable). I mentioned when I started crossdressing, though skipped over the first time I thought I might have been trans.
Before the end of the session she asked if there was anything specifically on my mind. I just said gender, identity, where's the line between crossdressing and trans and mentioned that while I don't have dysphoria, I do think I might have euphoria. So at least she's aware of what's going on in my head.
And until next week, a week to think, worry, and relax.
I'll add that I'm considering asking her to use my girl name because even though I'll be in boy mode, I do want to get used to thinking "that's me" and seeing if it fits. Not sure if that's weird or appropriate.
Thanks again, and know I'll be annoying on here and continue to ask a lot of questions (often and sometimes maybe mundane and silly).
