Lesbian sex-ed/advice?

Ok so I'm 16 and I have a gf but I just feel like theres so little information on being a woman who loves women. They never taught us anything in school and theres not much out there on the internet (I've found the basics but I had to really dig since most of it was just "do what u want uwu"). I dont want to get my information from porn because

a) from what I've heard its hella unrealistic and made for the pleasure of straight men and

b) theres a lot of sex trafficking within that industry so I don't want to support it

So, because of that lack of knowledge i wanna know, what's something you wish you knew about lesbian sex? Here are a few questions/concerns to work with

- how exactly does tribbing work? I've only ever heard vague descriptions but it sounds fun

- best position?

- we take turns with pleasuring eachother right?

- my gf is clean and I'm a virgin who hasnt even kissed anyone else so I shouldn't have to worry about STDs right?

- what do I do to my pubes?

- I'm scared I'll be bad at it and won't satisfy her, how do I handle these feelings?

Thanks for reading!! I hope to start a dialogue on queer sex ed as well as find some answers for myself
