So, the name on my ID is Jonah Mateo (legal since August 8th 2015), but different people call me different (nick)names and I just wanted to make a post about those names with some "explanations":
Appropriate names to call me:
• Joe
Most of my friends call me Joe, also some family members. I actually used "Jo" shortly after my realisation / coming out to myself as a short form of my birthname (you can't deduce my birthname from this) when I didn't know which name(s) to choose.
I really like it and I really felt like a Jo(e) so I looked for a name starting with Jo... I didn't want to have a very common one (like Jonathan - I really like this name, but I know some Jonathans) or old one (like Joseph) so I found Jonah and chose it.
Later I found out that it's gender neutral, but I had chosen a second (definitely male) name before anyway.
I also started using Joe because it looks more masculine (and better ^^).
• Mateo
I actually wanted my second name to be Samuel because I really like the short form (Sam of course), I just really didn't feel like this name would fit me. So I talked to my mum about this and she suggested the name Mateo because she likes it and also thought it would fit me. I didn't even think about it for long and changed it (already during the process, but that's no problem).
I wasn't using this name until the trans workshop weekend in September last year. There were so many non-binary people and because Jona(h) is neutral there were quite a few with that name. So because I wanted to feel special (*cough*) I used Mateo there and I really liked it. After the weekend I started to use the name on the Internet more. I didn't ask my mum / family to use it because they had already had the first change.
So yeah, I really like this name. ☺
• Joey
• Matt(ie) (English pronounciation)
• Jonny
• Jon
Inappropriate names to call me:
• my birthname
Well, that's kinda self-explanatory. I mean, I really like my birthname, but - as in a post some time ago - just don't use it when referring to me.
• Jonah
Only my mum and my close family calls me by my full name and I kinda dislike it. I don't really know why, but I kinda regret chosing it in the first place now. I should've just used Joe as my first name...
• Matty (German pronounciation)
That just sounds stupid.
