Do it too often and with high water volume and it will fuck with your intestinal bacteria and can make you ill. Doing it every single day for long enough apparently makes your body cease shifting poop because it expects a free rinse to do the work for it. Apparently doing a dozen enemas in a day can even skew your electrolytes and hospitalize you. Point is that too much of anything is harmful, if you somehow chugged nine litres of filtered water you'd still die even though water is harmless to swallow unless it goes into your lungs.
>Did I just make a huge mistake?
No. Just stick to doing it every two or three days, and don't pump yourself totally full. All you really need to do: have a normal poop; wait about an hour to let things settle, and make sure it's all out; rinse around a little until the water comes out clear, 2/3 times should do; then wait half an hour and try pooping again, as sometimes water gets stuck up there; then get to buttstuff.
Also >>248832 is right, a healthier diet and a good poop is all you really need. If you're fucking a guy just poop and wait a while, then have him wear a rubber to prevent poopdick.
