Need info for my story (hetero or lgbtq+)

So, i actually want to make a manga/comic abt some cool things and all that shit lmao

The thing is, i wanna know from experiencied ppl (cuz i feel like that would help me a lot) things like, people that consider:

themselfs genderfluid:
- how it "works"
- wich pronouns you prefer
- what clothes you decide to use (i actually believe that clothes don't need gender so i feel okay with girls wearing suits or guys wearing crop tops and skirts, y'know?)

-Aromantic people (in general)

How Homosexual relationships "work" (i also know its bad to use this tittle but like i don't know how to explain it) for both gay and lesbian couples:

- Do every homosexual behaves in a sort of way, or do they mind certain actions?

i honestly feel like im expresing myself pretty bad but i do it for the sake of a good story and don't fall in BL/GL clichés at the time of doing a love story
also, it's okay to vent here and sorry if something came off as rude... i hope someone can answer any of these questions! (▰˘◡˘▰)

And another question set aside the last topic, do u think that being sexually atractted to a transgender person denies their gender?

For example, A girl falls in love with a B girl wich is going trough transgendering (if thats the word) , but in some sort of way, A is still heterosexual, but does that mean that A is denying B's indentity? fjwahfjah this is too long
