When a tampon is inserted correctly, how much of the string should be departed flaccid outside the vagina?

I've tried to insert one numerous times and never know if it's in right.
I know it's within correctly if you cant feel it, but how much of the string should be departed showing outside?When a tampon is inserted correctly, how much of the string should be departed flaccid outside the vagina?
tampon should start about a partly inch into your vagina, like your vagina should sort of close around the tamon so that you can sit and lift up your legs comfortably. I still do it wrong everyonce in a while and enjoy to push it up a little more or pinch it out.
enuf so you can pull it out
Once you insert it you shouldnt perceive any pain when you move around or try to sit if you do afterwards you did it wrong
a couple inches
most of the string
All of these girls have angelic answers. And yes i'm 23 and i still get it wrong sometimes and hold to try again, it's normal.
