I am going to have to nitpick here: 1) there's no way your cup could ever get stuck; 2) if somehow it DID get stuck: a) relax, like literally, b) maybe wait a bit (because um... it's easier to take out if it's not empty), because anyway c) there is absolutely no situation (other than it leaking, in which case it should come out super easy) in which the cup removal couldn't wait until the end of the business day when you're in the privacy of your own bathroom. Trust me, that thing can stay in longer than the official time on the package, and you totally won't die or get TSS or anything. ...Not that I've ever forgotten it was in there or anything... Oh, also, 3) there are, um... suctional forces involved there, so having someone else try to get it out sounds like a TERRIBLE idea.
And now back to your regularly-scheduled not-TMI-on-female-anatomy thread!
