Even if you portray the in game avatar as enthusiastic, some people will get the ick.
Well, there are a lot of scenes which gave me the ick, to be honest. Especially the patch 6 Spawn kiss. Or when he is telling Tav, that he loves him in the graveyard scene and Tav is behaving more like Astarion then Astarion himself. I wish I could erase those scenes... also there was a moment with Gale.. terrible (and I do like Gale).
