Just in case u guys are wondering, i am 16 but i have a little sister who is 12 and she accidentally stole one of my ex's porno videos on masturbation. so one day she was like "Can I masturbate too?" and well... uh i sort of told her no and threw away the video before my parents found out and bribed so she would't talk about it in front of the parentals but it kinds got me wondering... could she masturbate with no more risks than me?
