I think masterbateing is a good thing to do when you re in bed or in the shower. I'm 11 and I started to masterbate when I was in 3rd grade and I didn't even know. I looked it up when kids at school said this kid did it so then I realized that i was masterbateing
Just keep it to your self... make sure u always do it in a private setting. And don't become OBSESSED with it!!
