Scared of using tampons for the first time?

I can use tampons but haven't used them while swimming as I am scared that it will leak and expand inside me as it dose if you put it in water. You can get lubricating gel also known as k-y jelly which makes it go in easier and it doesn't hurt. Take a deep breath in and as you breathe out focus on relaxing the muscles around your while slowly inserting the tampon on an angle towards your back bone. It helps to have one leg up on the bath or toilet seat and one of your hands separating the skin around your . Hope I helped
