I've been researching cups for a while now and finally got my first one this week (size 1 sckoon cup). I'm familiar with my anatomy but am a virgin, and had trouble with getting it in-finally got the triangle fold to work, but it didn't open all the way and has shifted so that I can't quite find the stem. I can feel part of the cup when I bear down but am too tight to get a finger and thumb up there with the folded up cup to pull it out. How do I get this thing out, and how can I keep this from happening again? Thanks.
