It's worth submitting bug and/or feedback reports for wonky animations, yes; if there's something that just doesn't work, make a report. Larian are indeed fixing animations across the board, bit by bit, and there's along way to go, but we can never be sure if they've missed something, or if it's just in the queue - better to report and be told it's on their list, and to not, and let it potentially go missed.
It's odd, because I always felt that Astarion, in all of his dialogue and discussion, was coded as male-leaning in his general characterisation (all characters are player-sexual, but some have distinct leanings in one direction or another, as they are written).
