These are answers from Mares - On heavy play days: eat light the evening before/ day of, lots of fiber for days before. The day of, a couple hours before, a deep clean out using my shower shot enema setup (in my experience, bulbs are only good for a quick clean out followed by immediate short-term play) Deep cleaning takes some time, and I use a toy to ensure everything is good to go. Chill for an hour, revisit the shower before I leave- just to make sure everything has settled out (including clean-out water). Good to go and deep play for hours. - In truth, it’s trial and error with your own gut. Metamucil is key and I usually fast for 8-10 hours before a big event. Then a couple hours before, I will have a meal, nothing to heavy, a sandwich or such. That does 2 things: when you eat, it stimulates your colon so that meal can help with your final clean out. And also, never go into a long sex event starving. You will be weak and won’t perform well. With the 8-10 hrs fast, for me, that usually guarantees that my last meal comes out so I know I have a long window of pristine playground.
