This is a tricky question! There are a few reasons why, and depending on the nature of your question, it might be more of a parental permission thing rather than a body thing. So let’s address the parent thing first…

Just so you know, there is no minimum age for tampon use. It takes some familiarity with anatomy in order to place a tampon and you have to remember to remove them after 8 hours (that’s the longest it’s recommended to leave a tampon in) but those are kinda the basics. If your parents have concerns about tampon use, it’s an absolute myth that you have to have sex before using a tampon. There is no connection between sex and tampons. The only issue MIGHT be the hymen.

The hymen is a piece of tissue that surrounds the vaginal opening. The majority of hymens are just skin flaps that line the edges of the opening, but sometimes the hymen can form an extra skin bridge (called a septate hymen) or it’s possible that it only has tiny holes rather than one large opening. In these cases you may experience difficulty putting a tampon in. If you’re not comfortable taking a mirror and looking, have your doctor take a look and see what’s happening with your hymen.

Another reason you might have difficulty placing a tampon is because your vaginal muscles are too tense. It can be scary putting in a tampon for the first time so it’s natural that your muscles tighten up. Try to remain as relaxed as possible. In a seated position or with one leg lifted up on a ledge, try inserting toward your lower back. If it helps, remember that there’s nothing to be scared of.

Lastly, it’s possible that your vagina is a little dry and the friction can make putting a tampon in more difficult. If you are interested, water-based lubricants can help moisturize the tampon and vaginal walls and help you with inserting a tampon.

If you still have a hard time with a tampon, chat with your doctor.
