For girldick, if you mean for The Manager, best we can do is shrink her penis as of now once futa content is added. When a better workflow for tweaking the model is sorted, foreskin and other finer details can be added in the distant future.
If you mean for the player, that's a bit easier to implement. But if you can't wait, you can add the text file yourself to the Content folder so you receive the commands you want.
