*Early* LKH is chalk-full of sexual tension, but really isn't porn. Anita starts out, if you recall, as a Godd Little Catholic Grrl Who Doesn't Believe In Sex Outside Of Marriage. (Okay, yes, technically she's Episcopalian, but only because the Catholic Church excommunicated her supernatural ass--she still pretty much thinks of herself as Catholic.) So the first 3-4 books in the series are decent examples of a harder-edged romantic subplot with a resistant protagonist.
