How do I tell my mom without her freaking out?

My questions is: Why do you have to tell your mom? A girl can have a private life and that's definitely true during teenage years. At school? Take a trip to the bathroom or don't do it at all there. Wait until you get home. The anticipation of how great it's going to feel when you get home makes it that much better!!

Hi. you dont have to tell youre mum you have been masterbating. you should be able to have your own private life and enjoy masterbating.
masterbating is completely normal and it is no one elses bisines to know about your personal life.
so, enjoy your sexual play and have fun :-D
