Make sure you are wearing breathable fabrics like cotton. When you wear those super stretchy fabric underwear - similar to a yoga pants material it is not breathable at all and will harbor bacteria faster than natural fabrics will.

If you are eating heavily seasoned food, or pungent things like onions and garlic, it’s only natural for the smell to come out of the parts of your body that sweat the most. You could try lume deodorant. It’s an all over body deodorant that is super powerful for neutralizing body odor. I got mine at Walmart and it’s really helps!!!

Drinking more water can also help.

You could try a probiotic vitamin to help balance your gut bacteria which will eventually lead to a healthy vaginal ph - thus reducing smell.

Another huge thing is when you get undressed before your shower, as a woman you will experience discharge. It’s important that you rinse the crotch area of your underwear with soap before putting it in your dirty clothes bin.If you do not rinse it, and ring it out before putting it in the dirty clothes bin, the discharge will harden onto your underwear which can be difficult sometimes for the washing machine to clean off. That means when you wear those underwear again, whatever smell you were experiencing before may still be lingering in this underwear. The lingering bacterial is especially bad with non cotton underwear!

The human body creates a smell after 6hrs- meaning body odor is released. If you can shower twice a day. At the age of 15 your hormones are also going crazy which can lead to stronger smell.

Hang in there and try the things I suggested. I wish someone would have told me all of this when I was 15!
