Jordan is right, 9.5 inches is very large but not necessarily at the point where it's necessarily a hormonal thing, if it doesn't keep getting larger throughout the rest of puberty, it might just be what it is -- but he should keep an eye on it because if it is a hormonal imbalance causing it, he'll want to get it checked out. Other signs could be unusual hair growth for his age and stuff (e.g. 13 year olds don't really have much facial hair but if he did???) Who knows, might be nothing.

Also, yeahhhhhh.... those exercises are a bunch of boloney. If you're a man, you're going to get whatever size of penis you get, doing curls but with your junk isn't suddenly going to make you large like a porn star and most of the supplements aren't going to make a difference either.

As for accessing birth control, you can solve this by finding a planned parenthood or other local health unit. They typically offer free or subsidized birth control (I've had friends get it for $5 or so). There will be a public health nurse there who can educate you about the best options for you. As it is subsidized, they won't need insurance -- not where I live and I think the US is mostly the same in this small aspect.
