You could try a glycerin suppository instead to help get it out. Sometimes I find swirling my hips, like a hoola hoop motion kinda helps get it out. Pelvic floor exercises might be more useful for you to try and get the stool out. You could also try putting your feet on a stool so your knees are higher than your hips - sometimes it helps! Could including more insoluble fibre maybe help - sometimes I find too much soluble fibre makes mine too soft.If you do have a problem passing stool even if its soft you could have a problem with your pelvic floor, you could ask if your doctor can run some tests for ya.
