There could be several reasons. If you are young it's possible that maybe you aren't quite 'developed' yet. Are you using the super absorbency ones? Im in my late 20's and those hurt me. Read the box, it has info on tss that you may learn something from.
If she can't get it out she has to see a doctor. It can only get as high as the cervix so it wont go anywhere.
The tampon goes all the way into the vaginal canal - if that's what you mean by the muscle, as the vaginal canal is essentially a muscular tube. The whole tampon goes into the vagina and quite deep, it wouldn't even be near the vaginal opening once it is inserted so certainly wouldn't hang out. All that hangs out is the tampon string for easy removal, that is if you use a tampon with a string.
A tampon cannot really get stuck at all. A tampon can go no further than your vaginal canal, it can't be pushed any higher than that. As long as you are using a tampon and relaxed upon removal the tampon will come out.
first off whats it on... could be a gasket in the way!

You need to relax - if you're tense vaginal muscles tense causing the vaginal canal to tighten - try masturbating as when aroused your vagina relaxes, lubricates, opens, and increases in size. If there's a chance the tampon isn't full enough then try sitting in a shallow bath and help the water reach the tampon so it can fill-up and soften. If you still can't remove the tampon then you need to go to a doctor or hospital as soon as possible to remove the tampon to reduce risk of Toxic Shock Syndrome.
Going swimming won't cause the tampon to get lost in your body. The vagina is a dead end, and the tampon has nowhere to go.
If your tampon tears - which rarely happens - then all you need to do is insert your fingers vaginally to remove the rest of the tampon. If it's just a small bit of tampon the vagina may clean it out itself, but otherwise you should go to your doctor to remove whatever is left if you can't remove it yourself.
