'Dude' was one I got a lot even before transition. That happens when you and all your friends are stoners. I like it, but it feels pretty gender neutral to me, lots of girls I know call each other dude too.
Just hearing the right pronouns makes me happy... man, homie, bro, and such all feel nice, but for some reason make me a bit nervous too. Something about feeling inferior to other guys that I'm not really able to articulate right now. One that I quite like is 'boy.' My friends call me that sometimes, mainly because I'm younger than all of them I guess, and it feels good. Validates who I am but still sounds cute.
