I have this headcanon that's actually kinda several headcanons where Zuko comes out to the gaang and it's just like
Zuko, Prince of the Fire Nation, Heir to the Throne, Incredibly Repressed and Visibly Anxious: I like. Boys
Aang: .......well who doesn't?
Toph: me
Zuko: WHAT
Sokka: not everybody's bi, Aang
Suki: I am :]
Sokka: yeah me too but
Aang: wait, you guys have words for that?
Katara: you don't??
Zuko: guys I'm gonna have a stroke can we rewind,
Aang: I asked Monk Gyatso about it once and he said to love who you love, and whoever that is will come naturally :)
Zuko: Azula called me a slur
