I mostly use Chev or Chevalier online, as it is greatly preferred. I won't be mad if you called me Asiya or Christian though.
If we are more than acquaintances, and if I tell you my legal name, you are more than welcome to use that. But for outside purposes, you're required to use my online name.
He/Him if you don't know me. I'd prefer if you only used She/Her if we are, again, more than acquaintances.
For terminology, I only use masculine terms. Feminine terms are greatly discouraged.
For labels, I identify as a transmasculine aroace (butch) lesbian. I am not a male and I prefer to stay unlabelled in terms of gender identity (I also don't like to put too much thought into it.) I present fully masculine and I would appreciate if you viewed me as such.
I do not support lesbian transmen. I am not a transgender man.
