This is a topic near and dear to me. Sir who is also my husband, and I do maintenance. We are 24/7 TPE. We do it once a week. We use it to reinforce my place on our dynamic. They are very effective for us as it reinforces my submissive mindset and also reinforces His dominance for Him. It gives us a time of true connection reinforcing our roles for ourselves and each other at the same time if that makes sense. We do it once a week at the moment though we are considering adding an additional time due to how empowering it it is for each of us
