A tampon goes in the vaginal opening, which is located between the urethra (where you pee from) and the anus (where you poop from). The vaginal opening usually looks more like an oval-shaped slit rather than a round hole. Menstrual fluid flows from the vagina, so this is where a tampon should go. Most tampons come with a plastic or cardboard applicator, which makes it easier to slide the tampon into your vagina. Push the tip of the tampon into your vagina, hold the tampon’s applicator with your thumb and middle finger, and push in the back of the applicator with your index finger. You’ll know the tampon is in correctly when you’ve slid the smaller piece of the applicator all the way into the larger one. Once the tampon is in, you can throw the applicator away. Some tampons are available without an applicator – you can push these tampons into your vagina with your finger. It’s important to note that it’s virtually impossible to put a tampon into the wrong hole. There are three holes in that part of the body – the vagina, the urethra (where wee comes out), and the anus, or bum hole, where poo comes out.
