That's not where poop lives. But if a laxative enema is the only option at the store, it's easy to swap out the solution for a homemade version with less adverse consequences, sex coach Charlie Glickman, PhD, wrote for Good Vibes. You'll want to do the anal douching at least a few hours before you have anal sex to make sure all the water comes out. It might just be something you have to deal with if you're interested in anal. That's totally understandable, it's something that can be present during anal sex , and it's not exactly glamourous. Just be careful not to buy an enema that comes with a laxative solution because that could just make your situation worse. So you want to try anal sex, but you're freaked out by the probably inevitable reality of poop.
