I don't mind it as long as it's tasteful and not too crude. I've read Charlaine Harris' Southern Vampire Mysteries and there's quite a bit of sex going on between the pages but it's all tastefully done so I don't cringe. On the other-hand, I read The Birthing House by Christopher Ransom and it was pretty coarse, bordering vulgar. I skimmed those pages and it put me off the book as a whole.......ewwwww! Just thinking of it gives me the creeps!
Maybe women write sex scenes better than men? Or maybe it was because the sex in Charlaine Harris' series was from the point of view of a woman whereas Christopher Ransom's was from a male point of view, therefore being a woman myself, I could relate more to Harris?
Do you think it depends on the sex of the author?
