In regard to straining and wishing not to; whilst sat on the toilet and in need to pass a motion; try blowing your nose!
Yeah, sounds weird, I know; and it may not work for everyone but it’s worth a shot.
i don’t have issues emptying my pouch, nor do I need to strain but on one occasion whilst sat on the toilet, I just happened to blow my nose; and whilst doing so, without any conscious effort from myself, I opened my bowels, so to speak.
I’m able to blow my nose in normal circumstances, whether sitting. standing or lying down and without fear of accidents.
