What country are you from? I thought you were from England... I've talked to several from there, and although couldn't be sure, I thought their secondary school was "high school." I really ought to look stuff up.
And who knows about the parents. You're young. For all you know, your parents are into kinky stuff themselves. And yea, you have a bit to go before you can even consider it. But hang in there. Nothing wrong with fantasies for the moment
