I guess this means that the "Story of O" with 15 year old Natalie would be OK since she doesn't actually do it, all she does is watch.
"Return to the Chateau" is out because Nat and Sir S make it in a brief paragraph.
A fortunate choice, the original story was much better than the sequel, Good thing Pauline Reage isn't an active writer on this forum, and come to think of it She's dead now so we don't have to worry about it.
I'm sanguine with an elimination of kiddy porn, it never did anything for me.
If you're mesmerized with youth you can describe it (teenager) without dating it (18). I don't think we'll need to state that all fictional characters are at least 18 fictional years old.
Come to think of it I did that in one of my stories but had to take it all back cause Bruno was only 6, though that was 42 in dog years so he was an adult right?

Hope that clears things up...
