Well for me, it is multiple things l believe. It is the anticipation, the preparation, the insertion of the nozzle or tube, the filling and holding then the blessed release. Even if it is a solo excursion, l always think about getting my enema for a bit before l begin to put it together. My pulse quickens while l am mixing the solution, whether it be just plain water, soap mixture or salt n soda.
Then l contemplate which nozzle or tube l am going to be using. Then up on the bed l go. Assume my position, on my side, back or butt up. Then comes the lubing of myself. 1 finger, 2 fingers, sometimes 3 if l am feeling really naughty!!! Then in goes the delivery system. Deep, slow, smooth and here comes the beloved water!!!
I feel my belly swelling, pressure, slight cramps. More pressure, making me wet. Sometimes l act on it, sometimes not. Depends on if l am planning on more bags, or just this 1.
I hold it for as long as possible, sometimes with a plug, or if l am using an inflatable nozzle or 1 of my larger nozzles, let it do its job.
Then time for the release. Move myself to our bathroom. I sit, then remove the nozzle and let it go. Sometimes its now l act upon my earlier feelings and as lm expelling, lm rubbing myself or using an electronic associate to the blessed climax of the event!!!
And this is just by myself. Then there is all the fun l have when with others to help me along my way!!!
