As for men, every woman is different. I'm sorry if that's not the answer you've been waiting for, but I don't think there's really any advice to be given before starting to go out with women ... apart from those one gives for all relationships in general: respect each other, etc. .
I may be wrong, but I have the impression you think that, for example, if you meet a butch (masculine lesbian) you will have to behave in such a way, with a more feminine lesbian (also called "lipstick ") in another way, etc. because I imagine, with what you said, that you have not rubbed a lot of LGBTQIA people. If you think more in "individual" than in "cliché", you will put less pressure on yourself. Stay yourself and behave with the women you meet as with any other person you may meet. And as with all other people, maybe it will not stick with some, but very good with others! ;-)
Well, I hope that what I wrote will help you in one way or another.
Good luck! :-)
