Experience with hive tunnel hollow plugs?

Recently got one of these hollow plugs to hold me open while expelling a four quart enema.

It’s pretty big and a good challenge to insert with the pressure of four quarts inside. Initially a big rush of water comes out, but then it stalls out. I think it’s putting too much pressure on my colon or something and prevents the rest of the solution from flowing out.

I’ve tried turning it or pulling it out a little bit but it doesn’t seem to create a clear channel for things to flow.

Anyone have ideas for positioning it to create a clear channel for things to flow?

The problem is that the rectosigmoid at the top of the rectum is held closed by inter alia the puborectalis muscle, a sling that goes around the top of the rectum and which is part of the pelvic floor muscles which are involuntary i.e. we don't have direct control over it. The only way to get "free flow" outta yer arse will be to use a hollow plug which is substantively longer and which can be pushed through the rectosigmiod junction into the sigmoid colon itself. It's not too difficult and is quite safe if the plug is flexible and rounded. You will need some practice to get this done without too much discomfort, if this is your first attempt at getting into the sigmoid colon.

Just be sure to be on the toilet when you do the deep plug insertion - the explosive start and continuous flow directly from the sigmoid colon when you "breach the gate" will certainly be a messy disaster to clean up if you miss the bowl....
