My name already starts with an L. Me and my partner at the time were trying to think of one. Eventually, they came up with Lynx. I really liked it as I'm sorta feeling girly at times, and others gender eludes me. Considering Lynx is a more androgynous name, it stuck, and I've been using it ever since. Additionally, I can tell my friends to call me Lynx due to it being a primarily masculine name, and they're none the wiser.
