Regarding this, should you be able to feel your tampon a little?
No. When a tampon is inserted correctly (pushed far enough in) you won't be able to feel it. Tampons are designed to be worn in the upper part of the vagina, the part furthest away from the vaginal opening.
Secondly, how do you know if your tampon is the right size? Ideally, a tampon should last about 4-6 hours. If you remove a tampon after 6 hours and it still has a lot of “white” showing or it's uncomfortable because it feels dry, you should go down a size. If you fill or overflow a tampon in less than 4 hours, go up a size.
Also asked, how far should I stick my tampon in?
Insert it as far as your middle finger and thumb, at the grip – or middle – of the applicator. Once the barrel is comfortably inside, hold the grip and push with your index finger on the smaller tube to push the absorbent part of the tampon into the vagina. Push this until it meets the grip and your other fingers.
Should a tampon slide in easily?
Wiggling the string while bearing down should help the tampon move at least slightly down the vaginal canal. Once the tampon is close enough to your vaginal opening that you can grab it with your fingers, gently and slowly wiggle the tampon from side to side with your fingers as you pull downward on it.
