I’m not sure if there’s a higher percentage of trans people who are otherwise LGBTQ+, although if there is, perhaps it’s due to the increased self-exploration surrounding gender which may lead to exploring sexuality. I personally feel like if I’d been cisgender I would have a different experience with my sexuality, as questioning gender stereotypes/roles led me to also open myself up to the possibility of different queer sexualities.

Ehhh its a lot more diverse then that, i think you're just looking a little too much into it
