Larian Studios Forums Baldur's Gate III Baldur's Gate III - Story & Character Discussion Is Astarion really a pansexual?

I'll just point out that "Handsome" doesn't incline that it's necessarily a man he's talking about. This term has become something we see as very masculine even though it really isn't.
Minthara even makes this point in the game when you click a certain mirror and she goes something along the lines of "This would have been a beautiful mirror once, and I would have struck a handsome reflection"

There's also banter where Astarion tells Wyll he'll only come to his wedding if he can sit next to Mizora, and he says this in a very flirty sort of manner.

Stephen Rooney ( the writer of Astarion ) did say in an interview that Astarion did manifest himself as "a man of all the appetites" very naturally, and I can see this, personally.
He's here to live life to the fullest, all things considered.

I don't know, I can see where you're coming from but I think there's plenty of indications in the game that he's leaning both ways, as he was intended.
