Honestly this is the biggest issue in the game for me right now, it really puts me off having the animalese dub over the sex scenes, so I took it upon myself to make a little workaround for that on the last patch. Figured I'd share it.
I took the old sex sounds from an earlier version and pasted them over the new voice files. Should work with any version that has the animalese dubs (Tested with many 20.11s and the latest 20.12 + patch1)
Overwrite the files in Audio/SE with the files inside this rar and you should be good to go. I did a pretty lazy job on this, so it doesn't match 100% which princesses/races used which sound back then, and there's a little side-effect where princesses will moan when attacking in the overworld instead of using that little hi-yah sound (only princesses do this, progenies work fine), but it didn't bother me enough to go out of my way to address that.
