Tampon help please!!!!!!!?

Well for one thing, it can only go so far in there. The depth of the vagina only goes as far as the cervix. So don't worry about losing it in there because it can't happen. I've had a string break before and that's not even a big deal. You just squat, relax, and kind of push and it will be easy to remove. As far as the pain goes, you might just want to take some ibuprofen for that. Or it might be that you are putting it in wrong? Try using just plain original KY Jelly rather than vaseline. Tampons always hurt at first but then it becomes easier with time. You'll get used to it. You are still young. I didn't start using tampons till I was 20 because I was so scared of them.
