someone help me before I give up ):

😋😇💙
This is seriously about to drive me insane.. I'm one of those people that needs to learn things quick and be able to master it fast or I get so frustrated! Well no matter what I've tried so far, it takes me FOREVER to get my menstrual cup open inside of me, and each time I *think* it's open I'm not really even sure and a couple times it's turned out that it wasn't open. I can insert it just fine and I've tried different folds and I like the punch down fold the most. But I push and I squeeze and I twist and I pull and it takes me so many tries that my vagina gets sore from all the poking and prodding and suction :( what am I doing wrong? I insert it with the punch fold, and then before its all the way inside, I press down on the top of the fold to make it pop open, and it does, it just opens into an oval. It takes 101 tries to get it to open fully. WHAT AM I DOING WRONG? HELP ME PLEASE D:
