How does this work? Is it like inserting a diaphram? I cant use a diaphram cuz my vagina is too long and i can never get it out! Anywayz........isnt it messy when you remove it? How can you remove it without getting blood everywhere? Especially if you are in a public restroom. Do you fold it to put it in? Does it cover your cervix? I have alot of questions, cuz i havent heard much about these.
