Yeah, just after takedown, I was advised to hold it in, to kinda stretch the pouch, that lasted all of a day, maybe only a couple of hours.
Holding it in, not long after takedown, in my opinion is a little too soon, like I said, I did it initially but it was too uncomfortable, through fear of accidents, so I stopped and just went when I had the urge to go.
However, after a couple of months, once you've become accustomed to your new pouch; that's when you can begin to experiments, within your home, familiar surroundings, creature comforts, whith the toilet close to hand.
To evacuate the pouch, you kind of have no choice but to push, for myself, it's more like a sensation of letting go.
It''s kind of hard to explain; I guess rather than bearing down and pushing to empty, it's more like, when I feel the sensation or urge to go, I'm holding it in; not clenching, resisting or holding it in for longer than necessary and once I'm sat on the toilet and comfortable, I'm able to let go.
There's still an element of pushing, bearing down but not straining.
