What exactly is the difference between pan and bi? If they’re the same why was the pan label added?

That's how my niece describes it. I'm more inclined to men but I love both men and women so I class myself as bisexual. My niece is attracted to all genders, so she's pansexual.

 

Someone once made the joke to me that pansexual people are just super into the Greek god Pan, and now I can't help thinking about that. I'd totally part with that guy, I get it. It's kinda like how when I see "ACAB" I don't think "All Cops Are Bastards," I think "Assigned Cop At Birth."
