(And a good thing, too, it is a pain to lose the tampon strings inside the vagina and have to fish around for them.) If a
tampon hurts on pulling it out, it is because it is not very wet
with menstrual fluid. On a light day of your period flow, a tampon won't get filled. The cotton sticks to the walls of the vagina, and pulling it out can be a bit of a twinge. On the other side of the coin, sometimes a tampon can get saturated and you don't know, and it can leak through.
