I'm 13 and really don't know what's happening.. I'm too scared and embarrassed to ask my mom or my sister. But when I put a pad on or a tampon in I notice that I sort of push back and stretch my vagina lip... Things... And the weird and kind of scary thing is that the more I stretch it. The more it looks beaded on the ends! Like there are little tiny balls inside the skin! Is this normal?!
