Personally, I'm not sure animated sex scenes would in any way improve this game for me. To be perfectly honest, I often find them superfluous and boring, however many angles and speeds the Devs provide. Definitely not always, but often.
A lackluster or badly made animation for sex can ruin an otherwise nice build up to the scene and I find myself clicking through it impatiently.
I play different AVNs for slightly different reasons, this I play for the stories and the characters. And the pretty picks.
