Tampon question ....?

Hey, well i have the exact same problem. I'm 14 and I am Still not yet comfortable with tampons because of that pressure. I mostly experience it when im removing a tampon. It took me a while to think of an answers but think about, a tampon starts a small cylinder. Once the fluid collects and the tampon expands your going to feel some pressure against the walls of your vagina. What seems to help me is if I really relax my muscle when inserting and removing it takes away the majority of that tight pressure. So like the first answers says just relax so the muscle can loosen a bit to help the tampon slide out.
