The first thing I want to say is about the evaluation of the ascended Astarion kiss animation. The three new kissing moves are really sexy, but they also make me unsettled, because Tav/The Dark Urge's expression is not enjoyable, but looks very scared, as if they don't know why Astarion has suddenly changed his temper. And here's the paradox: Astarion's ascent was facilitated by Tav, who was the only one willing to lend him their eyes to look at his back. In a way, the man who made the pact with The Archdevil Mephistopheles was actually Tav. He/she knows that the ascension ritual is very evil, and still willing to sacrifice 7,000 spawns for Astarion's ascension, how can such a person be as innocent as a pure white flower? As Astarion says in the game: "Our hands are both stained with blood."
So, the fearful expression of Tav when kissing Astarion perplexes me. You knew the price of ascension and then you chose to be evil, and you became a spawn of Astarion. (If you regret doing so, you can read the file and go back to the non-ascension route.) Since I chose to let him ascend, then I am ready to be the villain.
The second contradiction: the mind detection check of the night of Ascension. Players who choose to let Astarion ascend know that on this night, they can detect Astarion's thoughts, revealing that Astarion believes Tav engaging in a romantic relationship with him is demeaning themselves, and he thinks Tav enjoys it. With this premise known to Tav, can Astarion's display of dominance be seen as catering to Tav's preferences? (Of course, I know there are also reasons to be affected by the evil forces of Ascension ritual.) But from this point of view, the relationship between Ascended Astarion and Tav appears to be consensual BDSM, so Tav's expression of fear is somewhat unreasonable.
