I haven't read her books, but I wonder if I'd be more jarred by the porn or the Mary Sueism of it?

I know what you mean, though, about the author becoming distracted. I've read fanfics where I thought the sex scenes were there because...well...they've got to be there, right? Everyone else's fics have 'em.

The first Harry/Draco fic - actually the first ever HP fic - I read had a kiss as its culminating emotional point. And I found that entirely erotic and moving. And there are a few current writers who still stop there and move me just as much.

Maybe that should be my new mantra: penetration not required!
