Japanese nicknames
My name is Alexander, and I've been treating Alex as my full given name. I dislike my name in Japanese as it is hard to pronounce, so I would like some help on that, too. My middle name is Lucas, my handle is lualdu, and my old nickname is Lu. Which leads me to the idea of ルウ. Just wondering if that seems too feminine. On top of that, I have no idea how to introduce myself with a nickname. E.g. "My name is Alex, but you can call me ___"
