I know this pergunta is odd, makes you uncomfortable, and possibly embarrassing......[For Girls]

you pretty much just stick it up your vagina... to be blunt.

I don't O_O
Do you mean the thing that soaks up the blood that you stick up your V?
Oh that1 I havent done it. But i know how.
Get the opposite part of the string end and shove it into the place where you gonna get bebês and Voila! done. to take it out pull the string which should be there. If you want an easier way (cos its gonna hurt) there a thing that you can insert it with....

Stick it inside your vagina

Pads might be simpler...I never used a tampon before ._.

the box usually comes with instructions, but message if ur confused :)
and dont worry, its a perfectly valid question!!!

Um ask your mom, or a close GIRL relative

All tampons come with an instruction pamphlet--but this is really important: make sure you choose the right absorbency. They range from "lite" to the dreaded heavy flow. You don't want to use a heavy flow on a lite day.

if u don`t want it to hurt use a pad there easy and they don`t hurt.

stick it up your v it will feel werid the first time you use it

Never used one before but I'm told that if you want to stick it in properly you should lift up a leg, remain relaxed (because it's harder to stick it in if you are tense) and stick it in.
