For a game that's big on representation, I'm a bit disappointed about the fact that there's no asexual route to take here. Especially when we have a very clear contender for this kind of relationship.
Astarion expresses how he can't enjoy sex and how his trauma has affected his sexuality etc. We do have this very sweet option to tell him that "maybe what he needs is a friend and not a lover". He reacts very fondly to this idea and all seems well. However, that's essentially the same thing as breaking up with him because it ends the romance. Why? Why not just add an asexual option here?
Maybe what Astarion needs is more than a friend, but not sex? Let Tav be that person for him.
If you didn't know, sex isn't the only thing that makes for a loving relationship. And to make it so, especially for a character who's essentially traumatized by sex, just feels wrong. Let him love Tav without sex having to be on the table.
Please
