Hi! I bought a Diva Cup and so far I'm liking it pretty well. The question I have is about the stem--is it ok to leave it poking out a bit? I am not sure I want to cut any off yet, since when the cup does ride up it's easier to get back down with the full stem. Just wanted to know if there's any important reason it SHOULDN'T be there, even if it's not uncomfortable at all.
