Long colon tube - Insertion methods

I am curious about the methods for inserting a long colon tube (100cm). Many years ago I had read that it is important to have the water turned on when inserting the tube, but there was no explanation as to why the water needs to be turned on. If I'm understanding it correctly, it's done to make it easier to insert the tube, but is there another reason?

What I want to achieve is to insert the tube as deep as possible by inserting a small amount of lubricant through the tube to facilitate penetration and only when I have inserted the entire tube to turn on the water.

I want the filling to happen from the top to bottom.

Will it be a problem if I do it using the method described above?

Here's what I do:

Put a large amount of lubrication around the anus and between the buttocks. This will lubricate the tube as it goes through and allow you to easily control the (dry) tube.

Pick a comfortable position to start. Insert and slowly feed in (don't press hard, you don't want to puncture your colon). As you meet turns in the colon try going in and out, breathing deeply from your belly, and changing position. Sometimes counterpressure helps (pressing over the tip of the tube to help guide it). Sometimes you may wind up opening the clamp and letting in some fluid as well. By the end I usually have been in left side, back, right side and knee chest - haven't tried prone, that might be a good one too. As you move around the colon shifts somewhat and this can help you pass the tube through.

My approach…before trying the colon tube, have a large volume enema to clear the way for the next step!

My system: inject 30cc mineral oil into the anal vault….grease the first 2” of you tube….insert….as you proceed the oil lubes the tube

Adding soapy water slowly as you go in farther opens the colon and adds slipperiness . An in-line pump helps get around bends in colon.

I used it with my 5’ tube reaching the cecum!

Having the water gently flowing makes sort of a roto router effect and helps clear a passage for the tube to advance. Go slow and gently pull back when you hit any resistance. That will help get the water way up inside. You may need to release and repeat a few times but well worth the time and effort.

In my experience the only downside is the water is so far up inside that you will need 2-3 release sessions so plan your time accordingly. The high enema with a long colon tube can be a very nice extended play session. Definitely great for extended deep ass toy play after too. Just go slow and enjoy the pleasure.
