My vagina hurts every time i put in a tampon what is the cause?
Soreness,dryness or you don't put it right.Read more carefully the instructions bcause if you put it wrong it is painful and uncomfortable..
could just be soreness/dryness. try switching to a pad for a few days.
You probably need to change the size, use one that is smaller. You can also use a lubricant to insert a tampon which will help alot.
