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.
Unless you go out and say what you stand for, other people will do it for you.
I got into shape because I took kick-boxing lessons every day to prepare for a fight scene with Taylor Lautner. I really wanted to lie down and eat Chinese food, but I kick-boxed every morning and ran. If someone was filming you with your kit off, you'd do the same thing.
