Are you trans yourself?
Why are you writing essays about trans people?
I suggest reading a lot more before deciding to write about us (unless this is for a school assignment and the goal is precisely to learn, rather than influence).
Particularly I suggest reading first:
- Julia Serano's Whipping Girl and Sexed Up (most of the questions you asked will be answered in these two books, particularly the first one)
- Gender Dysphoria Bible
- Leslie Feinberg's Stone Butch Blues
For non-fiction and memoirs to help you understand trans experiences:
- Janet Mock's Redefining Realness
- Mia Violet's memoir: Yes, You Are Trans Enough
- Jacob Tobia's memoir: Sissy
- Maia Kobabe's graphic novel memoir: Gender Queer
- Lewis Hancox's graphic novel memoir: Welcome to St. Hell
For trans novels that should help you understand the trans experience better:
- anything by Casey Plett (Little Fish, A Safe Girl to Love, etc.)
- Detransition, Baby by Torrey Peters
- Nevada by Imogen Binnie
