I personally don't think that would be the right solution. Having Astarion constantly adhere to what Tav demands like that would feel very unfitting for this version of him and give the impression that they are ordering him around, in my opinion. (I know there is a choice in the scene where he turns Tav, but that's a different situation than asking for a kiss, before Tav is his spawn, and not a repeatable action.)
