Let's see here - I was a very large girl (we're talking over 200 pounds) from 10-13 so I don't know if the rolls I had were just fat - or if my tits had actually sprung up. But when I was 13 I shot up from 4'11" to 5'4" and all that baby fat went POOF! It also helped that I was riding horses everyday - so not only did the fat go away, but the ass got really nice, the belly was flat and I was prancing around by the time I was 14 with a D cup up front and baggage in back. By the time I was fully grown at 17 (5'7" and an attitude to match) I had a lot to play with.
I never really had any funny stories until I reach 15 though. I was living with my Godfather at the time and his youngest son and I would go skinny dipping all the time. Nothing ever happened - but that doesn't mean that we didn't want it too. "S" was about 2 years older than me at the time and full of hormones, so skinny dipping with me for the first time that summer was an eye opener. For some reason he missed the boobs and butt that sprung out of no where. His older brother "C" followed us down to the pond and caught us. "S" got his clothes and went back - but "C" wanted to talk or rather scold me - so he sat on my clothes... until I walked out of the water and started stalking back to the house. He noticed then! I got my clothes back right quick.
I never really noticed it all that much - and as I did all my own shopping for undergarments (you try asking your Godfather for bras and undies and see where that gets you!) the men never really had to deal with it. I didn't have a girl to go shopping with until I was 17 and moved back to Texas and my Mom, and by that time I didn't want or need her help.
If you're talking about puberty in general - I used to delight in asking my father and Godfather for "personables". I always seemed to forget to get them... until my Dad came back with those boats they used to call pads - you know the ones you have to use a fucking BELT with? I remembered every time after that - although I did miss making them blush.
