When I got it, I did a few dry runs, basically just practicing getting it in and out. I wanted to do the origami fold, but couldn't figure it out (someday!), so I started with the punchdown fold. That worked pretty well, but it didn't pop open, so I tried the C fold, which I think I have read pops open more easily. Surprisingly, I did not have any trouble getting it in with the C fold! It looked huge to me at first, but so did the cup in general. I don't think it popped open, though. I have had no trouble getting it out, but I think that may be related to this problem.
Do you have any good techniques to get the cup to open? I have tried "swirling" my finger around, which didn't do much for me. I have also read to twist it, but how exactly do you do that? Can you use the stem, or do you have to hold the base of the cup? I have also read to use cold water on the cup, but I didn't try that yet. Is there a fold that opens easier? If I can insert it with the C fold, I can hopefully insert anything!
I think that I may have gotten it open once, but I'm not sure. Unless I'm totally confident that I am consistently able to get a seal, I probably will use it the first night of my period and only try it during the day if I get no leaks then.
One more question: I bought kiss my face liquid unscented hand soap to clean my cup, and I want to be sure that it's okay.
