I don't have any advice.
In fact, I recall specifically not caring about puberty at all.
I never wanted to grow up, and I specifically remember being confused at what people would do if they weren't playing with toys, but I'm change resistant and stubborn.
That being said, I started becoming extremely interested in girls beginning at about 7 years old (first grade, I specifically recall), so that was a non-issue for me.
Although, I think at one point my father thought that I was gay because I never actually pursued girls. Well, duh, it wasn't like I'd been that successful before I hit puberty, so I was pretty much tired of the rejection at that point.
