So, I don't dispute what she says about porn. Personally, I'm pretty selective about it: it has to be clear that all parties are consenting, has to not just be nasty bangin' away, has to bear some resemblance to people actually having sex and enjoying it. I'd say about 90% of it is pretty gross and 99% of it is unrealistic--including the amateur stuff.
Having said that...
OK, I tried the URL she spouts off and I get a 404. Not a surprise; she probably spouted it off on the fly. Probably. Nevertheless I did a Google search for "site:fanfiction.net harry potter nc-17" (fanfiction.com redirects to fanfiction.net) and got this story.
And apparently, Lavender and other students are writing erotica about Ron, which creeps him out because he has no feelings for her, leaving him feeling violated. Thankfully, though, Luna has rules in her fanfic! They are:
- If the couple becomes real they're no longer 'taboo' and therefore not fit for our 'fiction' any longer.
-No rape or non-con of any type in the stories.
-All stories must be rated M aka Nc-17
-All S&M stories must be clearly labeled as such to avoid upset. (Thank you Romilda!)
-All slash stories, whether m/m or f/f must be labeled.
-No incest stories! (In exception of the HAWT threesomes involving the Weasley twins.)
-No one under 15 mentioned in sexual situations. (This includes snog sessions Lavender.)
Well, good! No incest other than the Weasleys (because that's HAWT), and there won't be any erotica in this story about kids under 15.
I get that the age of consent is 15 in some places, but it's 16 in England. It's 17 where I live (Illinois). Anyone remember the shitfest when Glee did their Sadie Hawkins episode? Puck had sex with a 16-year-old girl who enthusiastically pursued him, wouldn't take "no" for an answer, and he finally consented despite not knowing that he was in a state where she was already at the age of consent? Nah, he asked her if would get him in trouble, she said yes, and he consented anyway. This of course means she was raped.
Chapter two of that story starts with some erotica fantasizing about Malfoy having sex with Ginny. I did the math; her character would have been 15 or 16 at the time.
But nah, they're not at all the same.
In fact, just doing a general Google search brings up a lot of fantasies about non-consensual sex and, well, there's some really terribly-written slash about Harry and Snape...you know...because there's nothing at all creepy about a teen having sex with one of his teachers.
So yeah...if I see an image or video of a 24-year-old in pigtails performing a sexual act, that's worse than fantasizing about 15-year-olds having sex? Or more to the point, nothing wrong with fantasizing about Bonnie Wright, at 15 years old, with her skirt hiked up, or a 15-year-old Katie Leung getting herself off with a broomstick?
I buy half of it. The other, not so much.
