Same here. Dd2 fancies girls. Not boys who call themselves girls.
She is attracted to other girls.
& whilst her lovely friendship group are very gung ho with the 'yeah so corvusdd2's a lesbian, Adam's gay, Parvinder's a bit bi but not sure, oh & Travis isn't a gay transboy anymore, he's a they & they are dating Victoria who is now a straight girl, despite the fact that everyone has known Victor since year 3'...
...the cracks are starting to show.
Dd2 hangs out a lot with a nice friend, 'Adam'.
So, say some of her year group, dd2 might like to consider that she's trans, because then she & lovely Adam would be a lovely gay couple, right?
Dd2: well, no. I don't fancy Adam because he's a boy & I like girls. Plus he doesn't fancy me because I'm a girl & he likes boys. Simple, no? Adam & I are both gay. So we are not attracted to each other.
Y10: but you are so cute together!
Dd2: my cat's cute. I am not dating my cat, or bloody Adam.
As far as dd2 is concerned, all things 'lgbtquia+' can take a jump off the pier.
She'd like a girlfriend someday, & she will be navigating that VERY much outwith of all things rainbow-y & Stonewall associated.
