Re: I have a question..
Don't be worried growth is different for everyone and in time it will all come together as you get older. Just be patient.
As far as your parents, my parents never said anything to me either. I'm 18 in a few months and all these years I've never had any discussion. Personally, I don't care that they didn't tell me. Saved me the embarrassment. If you can find all the info you need on the internet or ask here, why get them to talk about it? That's my take on it.
