Makes no sense whatsoever. A huge chunk of Act2 and the Act 3 (up to when you go to the palace) is him being celibate (and so are we of course) to get over his trauma. They wrote that, then ignored it on multiple occasions. It's not only Spawn Astarion, Ascended Asatarion has some diabolical voice lines for Tav that show at least one of the writers hadn't done any homework.
You're really left doing the thing I was hoping I wouldn't have to do with Larian - which is wait for modders to fix it (when did Bethesda take over?).
One modder has thankfully dealt with the worst of Ascended Astarion and Tavs dialogue (oddly it isn't what he says that's the issue its what Tav says - so no idea what Larian was thinking by that point).
But that damn dock scene is the absolute pits and should be cut out of the scene altogether and consigned to an incinerator.
