Instead of creating mods that the vagina can be animated with various other parametres, how about creating a mod tha the labia-vagina lips can be open by pressing a key in-game and close by the same key.How much they will open(how big the hole will be) and the key binding can be adjusted by MCM and the position of the vagina can be adjusted with bodyslide so it will fit the body.This way there will be a more realistic approach as the player can open the lips before,during or whenever and sex animation plays or any animation.
