Just wanting to test how comfortable the name is

Hello I am Alexis,

I am 27 years old and transfemme. I love video games, movies, computers, and fashion. I picked Alexis to keep in like with names that begin with the letter A. Would most certainly prefer she/her pronouns

I am a trans woman in the process of being true to myself and figuring out whether to choose Madeline or Tiffany as my first name. My assigned name is Thomas and I am 26 years old and pre everything, for context.
