Why is it so hard for me to insert a tampon?

Frankly,: It takes practice. If you are really really worried about it, you could go get checked out to make sure there was no anatomical problem...but it's just something that takes some women a little time to work out the mechanics.

Different causes: 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. try using a small amount of vaginal lubricant (K-Y Jelly) on the end of the tampon to help it glide in. If you are not able to insert a tampon after several tries, please see your Gynecologist.
