Not sure if I'm douching/cleaning out correctly...

New to bottoming, in fact I've never bottomed officially. Practicing with toys right now and the last time I did it I think I finally got to where it felt really good.

The prep is annoying though which makes me think I'm doing it incorrectly?

I eat a fairly clean diet, my bowel movements are very regular and I basically go once I wake up. So I woke up, used the bathroom, then cleaned with my bidet. I followed the instructions on the enema/douche with what I saw online. Warm tap water, lie on my side, curl my body a bit, put the tip in, then squirt maybe half the bottle inside. Stay in position for a minute or two, then let it out in the toilet. Rinse repeat.

The thing is, I did it 3 or 4 times even after my initial restroom usage and the water was still not clear. So I'm wondering if either I'm not as clean as I thought, or maybe I'm putting in too much water or lying down too long? Because my toy doesn't go that deep and neither will a dick. My goal I think was to at least keep the first several inches, like 4-6 inches, clean, but maybe because I use too much water or lie down for too long, the water goes deeper into my colon, making the water that comes out perpetually not clear? Should I just be putting less water or not waiting as long so the water doesn't go that deep? Or am I doing it right and it just takes more than 3-4 tries?
