Hi I'm 16 and currently having problems inseeting tampons I've tried 4 times already but still no luck so I'm wondering if there's anything that can make insertion easier

First, your vagina has a "tilt" so you have to take that into consideration. Angle the tampon toward the end of your spine, not straight up. Second, if your vagina is dry and the tampon is dry, it's nearly impossible to insert it without pain and screaming.

If vaginal dryness is a regular thing, try some of these ideas and also talk with your doctor about this, as there are other reasons you don't want dryness to be a chronic thing --

Boost your water intake. Your first step should be to check your hydration. We should all consume at least ten 8-oz glasses of water a day. This simple step can be surprisingly helpful.

Check the chemicals in your environment. Review the list of ingredients in your personal, bathing, and laundry products. Many perfumes and other chemicals commonly found in these products are irritants to the delicate mucosal tissues that line the vagina.

Follow a hormone-balancing diet. Give your body the support it needs to make and balance your hormones, starting with your nutrition. The low-fat, high-carb diet many women follow literally starves your body of the nutrients it needs to make sex hormones. The estrogen needed for vaginal lubrication is made from cholesterol, for example — something women on low-fat diets are severely lacking. You might also think about adding soy and flax seed, which are good sources of phytoestrogens.

Fill in the gaps with a medical–grade multivitamin/mineral supplement. All of us need top-quality nutritional supplements to support our diet, no matter how well we eat, and this simple step can ensure that you cover the missing gaps.

Try a personal lubricant. Some women achieve immediate relief from vaginal dryness and irritation simply by using a personal lubricant. You may want to give one a try while you wait for improved hydration, nutrition and endocrine support to naturally restore your own vaginal moisture. Vaginal lubricant products are now available in a wide range of formulations safe for use in this sensitive area of the body.
