When you are learning how to use tampons, it’s a good idea to use the “slender” size. It’s also easier to insert it when your menstrual flow is moderate to heavy as this allows the tampon to glide in more easily. Also, when you are nervous, your muscles tense up, which can make inserting the tampon more difficult. The more you relax, the easier the insertion will be.
If you’re not able to insert a tampon after several tries, make an appointment with your health care provider. One reason for this is that you may have been born with a very small opening in your hymen, which prevents you from inserting tampons. This is true in only about 2% of teens, but it could be a problem.
