It hurts when I try to remove my cup

So I tried to use like, 10 times, this cup, and I haven’t been able to pop it open. That’s not the problem, I know I need to try different folds and a lot more practice.

The thing is that I use the C fold (aka U fold) to insert it (which it doesn’t hurt). But when I want to remove it, it’s almost as the same shape as I inserted it (doesn’t unfold, stays the same) and when the upper part is almost out it hurts a lot.
I don’t think being a 23 y.o virgin has anything to do with it, though.
So It’s not the suction or anything, that thing, even folded, hurts my vagina in the removal part… Should I try a softer one?
