I love to poop too but instead of an enema I go the opposite direction. A few days before the day I plan to poop I eat lots of found that "bind's me up" so I have a big hard load up there. Then I take a few laxatives whne it's time to go the poop starts off log and hard so it actually presses against the diaper then by the end it's a soft, mushy mess that literally explodes into th diaper.
Hmmm, so lovely
