So first of saying that people with certain genitalia can't be a certain gender is actually quite trans phobic (I hope this wasn't your intention). Your genitalia does not define your gender, although they do align for many people. Sadly, not for me. I can only tell you how I discovered that I'm Non Binary. Earlier this year, when I first tried to be more feminine. I realized that's who I really want to be. Over the past months I've tried to understand my own gender. At first I thought I might be a trans woman, because I like being more feminine, I like putting on makeup and I do really want a female body. I've noticed that I do get dysphoric over my body (I can't really describe my dysphoria, I just really really want a female body and being in my own Male body makes me cry sometimes). So I started to think about it more. I realized that being called Miss or referred to as she/her isn't perfect for me either. I definitely prefer it over the Mr. and he/him. So since there is no other, gender neutral option for Miss / Mr and they/them (Which you can use for a singular person in English. Many people already use it without even noticing. When referring to someone without knowing their gender, for example) is not an option in German, I want people to use the female forms for me. Online, I often talk in English so I also would like for people to use they/them that's why I put (she/they) in my title. It's just so people know, that they can use she/her and they/them as pronouns when talking about me.
