It depends on your family history and weight/size. For example if your on the skinnier size you probably won't be very developed. But that is completely okay! If your on the chubbier side you could be a larger cup size. If I were to pick an average cup size it would probably be 30A-38A for an 11 year old girl.
At 9 years old he probably is not "big" enough for anything but a youth sized cup. Be sure to get the curved kind of cup, not a flat kind, especially if your boy is playing catcher!!!
145-150lbs .
They only measure adults and not flaccid penises. When flaccid it's for peeing only so if you can do that you're fine.
