Best way to stop any is to use the Purity Room. That room will make it so their "heat" won't go any higher and you won't get attack at all. It's the best room for a character i noticed that her heat goes straight too 75% the next day and then 100%. So in two days she is at 100% heat and will attack you at night. Another way is to just drain their heat away before you end the day. Just remember don't end the day with them at 100% heat they will attack you most of the time. I don't find anything wrong with it as the girls sometimes will come for you even if they are a futa or not. If you have the permit for them to do it with others it won't work unless they are a futa at 100% heat but still has a chance of attacking you as well.
