It only makes its way down to the rectum when a sufficient amount has built up and is ready to leave the body (basically, when you feel like shitting, that's the only time feces are in the rectum). It can also be found in the rectum if your fiber and water consumption is not ideal.
2. Ideally, you should be consuming plenty of insoluble fiber and water daily (just water. Infusions/soda/etc don't count). This results in ideal bowel movements that leave the intestine and rectum completely empty and clean. No traces left behind at all. You can get insoluble fiber from whole wheat products (bread, pasta) or a supplement like psyllium husk for convenience.
3. Avoid overconsumption of intestinal stimulants. Coffee, tea, yerba mate, etc. They're great, but they also speed up intestinal transit. This means that the food you eat is rushed through your intestine. This results in something kinda like diarrhea. Also bloating.
No need to quit these drinks entirely. Just make sure to not consume too much. How much is too much is something that you have to study for yourself. For me, 2 cups of coffee per day is my max, and I might even skip a second one if I know I'm getting dick later.
Coffee is the strongest intestinal stimulant. You can replace a first, second, or third cup of coffee with tea or yerba mate instead, and get the same benefits without so much collateral damage (there will still be some, but not as much).
Keep this info in mind and tailor your own daily infusion consumption according to how you feel they affect you.
4. It's normal for a bottom to be ready to take dick at all times simply by following the previously mentioned nutritional practices, but it's also normal for them to do a quick water douche before sex, just to be sure. This is usually done if it's been a few hours since the last bowel movement or if they're gonna be doing some serious anal acrobatics.
