Kids are all computer-savvy. Sit down and write to your parents on the computer. And just say, I have some questions and I'm scared. There's some stuff I don't know and I really need to talk to you about sex. Tear it off and put it on their pillow. They'll read it.
It's good not only to realize that you can't please all of the people all of the time, but that you don't want to. There's a certain type of reader that you don't ever want to write for.
