Help!!!!

Here is a few facts

I’ve never wanted date anyone cause I never want to spend time or think of anyone in a romantic and sexual way...but I fucking love romance ❤️ Anyhow my last crush was on this girl over the web. She did say she was a girl but she didn’t really identify as a girl or guy and I’ve never saw a photo of her. I’ve also seen girls and thought they were pretty and I rarely think anyone is pretty/hot. So how do I know if I like girls if I’m not sexual attracted to anyone no mater the gender?
