To be honest, it doesn't matter, as long as people use the proper feminine pronouns. So many people have gotten accustomed to calling me "Derk" over the years that it wouldn't be fair on my end to get upset at them, especially when a lot of them probably are unaware of my identity.
I have said previously that I prefer Angie or Angelica, but at the end of the day, only the pronouns really matter. Derk doesn't even feel like a "guy" name anymore, it's just a fun nickname that's been thrown around all these years that people know me by. ^_^
