I am wondering if I am using my cup right. I have used the moon cup A (the small one) once and haven't tried since. I folded it up as small as it would go and inserted it and it popped open before I could get it in fully causing great pain. When trying to take it out I can not for the life of me break the seal so I have to pull it out and then try and get the rim out (no easy task). I'm 16 and still virgin but really want to use the cup. Any tips on how to reduce pain 🙃
