Honestly being “demisexual” is fine if you want to ID with that label, but you’ve gotta recognize that it’s also something that MOST people experience, the vast majority of people don’t have a desire for sex with strangers, most people don’t have sexual feelings until a bond is formed, and only wanting sex with people you know well DOESN’T make you LGBT. It makes very little sense to put a label on it that sounds “queer” and alternative and then hype up this way of experiencing attraction as if people are systematically oppressed for not having sex with strangers.
A straight cis woman who only wants to have sex with men she has emotional connections with is just your average straight cis woman and benefits entirely from straight privilege and is not LGBT or queer in any way so jot that down
Demisexuality isn’t only wanting to have sex with people you’re in a relationship with, it’s only ever being attracted to people once there’s an established relationship.
Someone who isn’t comfortable having sex with a stranger isn’t demisexual.
Someone who is never physically attracted to strangers, ever, is.
There’s a difference between “oh, I don’t want to have sex with them, I don’t know them” and “why would I find them hot? I don’t know them”. People who aren’t demisexual look at other people and think “oh, they’re hot” in one way or another sometimes, people who are demisexual don’t.
