It's a plactic thingy that shakes or quivers(you pick since it is based on the speed). You know kids don't put that much thought into it. They just have a question. Sure it may lead to another but usually ends there.
My parents were great with me and the "sex" talk. Mom spent a couple hours one Saturday explaining everything. Next weekend, Dad gave me his take and then the 3rd Saturday they both sat with me to see if I had questions or to cover anything they forgot. What words did they say...beats me I was a kid. But I do remember that they cared enough to get me the facts before I was old enough to know all about it from my friends. Oh I forgot to mention, I had just turned 10.
