My mom has a heavy period and doesn't wear tampons because it would still leak to her pants.
Anyway, one day my day asked me, why doesn't she just very tampons? Wouldn't they just plug it up?
Yes. He thought that tampons actually plug up your vagina and stop any blood getting out. He was stumped when I asked him how he thought all the blood went away.
