Generally speaking, the submissive girl has greater needs. She needs to be touched more. Talked to more. Greater attention needs to be paid to her, especially if there are rules and guidelines outside the bedroom. She needs to know that her actions matter, that the time and effort she’s putting into pleasing you actually pleases you. You need to check-in, touch base, reassure; be diligent with your upkeep and follow-through. If you’re not, if she feels you don’t care, if your directives are empty… the dynamic will die. And if the dynamic dies the submissive girl is gone.
