I cannot hold my enema. Once I’m full and I take the nozzle out, I pant and get cramps and have to go. Any tips for holding it? And best holding position? When I got my first enema from a nurse she had me lay back with my knees up to my chest and she held my ass cheeks together which worked fine, then she had me on my knees with my butt up as high as I could, which also worked. But that was a small enema, and i have no trouble holding those. How do I hold a big one?
