Taking out your cup
Get comfortable, relax, sit down on the toilet or squat down and do a ‘poop-flex’ (tip from the video by Sarah Tran linked below, it works). Try it out and you will see the cup comes down to the point where you can grab the bottom easily with your fingers. A lot of people, over time, cut the stem shorter and finally cut it off entirely, because the stem may be uncomfortable. So, then you just grip the bottom of the cup itself which is ribbed for easy grip. For more tips see the videos below.
