You've asked this same question before little boy, go ask the little girl next door.
Avoid the confussion - wear a pad. And if you read the warning on the box, you'll find tampon use may lead to cancer.
Just google it. I'm sure there are probably 50 web sites explaining how to do that, with pictures and everything.
Leave it hanging out the back. It will really help if you get the runs......
that makes no sense at all.
Tampon use does not lead to cancer...I have used them for several years and have never seen a "cancer warning" on them. However, there is a warning for Toxic Shock Syndrome. TSS, can occur when you leave your tampon in too long, or not wearing the right 'size' (say if you are only bleeding a minor amount, don't wear a heavy flow tampon.)Once you go to the bathroom, take out the tampon...it's also a good idea to alternate between tampons and pads every 4-8 hours.
If you were serious about your tampon inquiry (which I doubt) all you have to do is buy a box and read the incert. It has detailed directions and information.
