Thank you. In version V2.1, the previous error was fixed.
But I discovered one more mistake. Mod does not work with non-oral positions (vaginal and anal). When Expand Dong is loaded, such positions can not be used in the game. In version V2.0 - a man throws away from the girl, when pleasure is equal to pleasureMinRange. In version V2.1 - the penis is not visible, and the game does not respond to mouse movements.
It would be nice to be able to disable the mod for non-oral positions in the settings file.
At any rate, the best way to figure out the length + width limits you prefer is probably to set pleasureMinRange/pleasureMaxRange + extraPleasureMinRange/extraPleasureMaxRange to low numbers and just keep pleasure above that, and set lengthGrowthRate + widthGrowthRate really high.
Feel free to message me if you need more help.
