Excellent advice from Rottencock. I follow it. The only two recommendations I would add would be these:
Buy a dildo with a suction cup and attach it to your shower wall so that way you can fuck yourself in the shower every morning after your baking soda douche to make sure you are ready for the day's first fuck and clean. I also pre-lube so the first cock slides in easily no matter the size.
Buy and use generic Metamucil daily. I get either the CVS or Walgreens. It helps keep your poop well formed and solid so that your douches are fast, neat, and a quick clean out.
I have done this for years and along with a modified vegan diet mentioned above you are always ready for that Grindr quickie fuck.
