I've read about inserting and removing menstrual cups, and it seems an awful lot like inserting/removing a contraceptive diaphragm. Is it? I know the menstrual cups are longer, but don't they sit in the same spot in your body? I have no trouble inserting and removing my diaphragm - I can reach the rim to grab it if I bear down. What does that say about the length/depth of my vagina and thus the type/brand of cup I should get?
Or am I totally off on the similarities between the two?
Thanks!
