Experimenting like that when you're young is common, natural, and harmless. Nothing to worry about. \n\nEDIT: Let me clarify something here: *pre-pubescent kids* fooling around and asking about each others' bodies is what's common, natural, and harmless. If someone is being taken advantage of, being manipulated, etc., or if the situation involves a kid and a teenager/adult/whatever, that is *sexual abuse*. I feel weird having to explain this, but apparently some people are confused...
