First diva cup, pls help!!

So I finally decided to try the menstrual cup, I bought the Luna cup over the diva cup because I read that it's more comfortable. So, today is my first day wearing it and it's not tooooo bad, but I can definitely feel that it's there.

My biggest problem now is removing it though. IT.SUCKS.SO.MUCH.

I pinch it like it says to, but it feels like the rim of the cup is just too big for my opening. I feel like I'm being stretched way too much. Is that normal? Is there a technique to maybe fold it so it doesnt come out while fully open? (I only have so much room!) I'm still sore from removing and reinserting it 10mins ago. Any advice would be appreciated!
