I started stuttering when I was a kid and it's been there ever since. I think we can safely say that these things vary (which is true in general for stutter). Don't expect it to go away once you're done with puberty. There's simply no good reason to assume it would be so (no guarantee, in other words). - Also: >one of my uncles stutter so that's likely where I've gotten it from You have no connection to your uncle such that you can "get it" (or anything else) from him.
