OK, I'm a bit young and I have an older brother and HES 14, and last week I was in his room and he was doing something and Grose asked what it was and m ', said he was masterbateing.
and asked him what he was and he told her when you play with you, and asked what he told me how girls and he said it was normal and everyone does. And then I tried last night in bed, but I feel nothing, I kept trying and when I left my father came, I thought that cuz I closed the door, but no ceilings on me! and he said it was normal, and then left, but I am soooo embarrassed cuz i know that they told my mother, and now he knows what to do these things !!!!!!!!!
