Not all of them have both hug and kiss options, though Gale, Karlach, Shadowheart, Halsin and Minthara can also be hugged as friends. I edited my inital post listing all epilogue interactions because I just saw that romanced Lae'zel in projection form can still be snogged. Wyll's smooch doesn't involve physical contact, but it's still some form of this type of affection. Astarion is literally the ONLY LI that doesn't have any kiss at the party!
Recently, I was also talking about the act 1 bite night how there is no option to actually enjoy Astarion nibbling on us (despite being able to tell him later that we did) and the animation only shows Tav being in pain. There's a vid of the scene with new camera angles and it shows even better how Tav is clearly struggling and likely just waiting for it to be over. Like it's a visit at the dentist or something.
Again, according to Larian, this is supposed to be the starting point of the romance, but there is nothing remotely romantic about it. Since they just modified the act 1 sex scene I want them to revisit this one as well and add a more intimate variation that we can select.
