Guys, so I was woundering if masterbation affects your period, like, does it make it not happen, girls usually get their periods between 10 to 16. I am 13, and I haven't gotten my full on period yet. I have had pms, I have masterbated and a little blood came out but, I have never needed a pad or even necisarilly a panty liner. I am woried that there is a problem with my body or something.
