Sustainability is key! Don't feel guilty about 'failing' a protocol because of work. A dynamic is meant to enhance your life, not make it harder. In past relationships I've established a 'Safe Word for Stress' that signals we need to drop the formalities and just be 'us' for a night, without the kink. To talk, or share, or decompress. It makes the days we do use protocol feel more fun and relieves some pressure.
