My own responses were: I prefer storyline and I like it to be more subtle so that I can fill in more of the details with my own imagination.
I like the more hardcore topics... and as long as the woman is being pleasured, that's fine with me
And finally, I like fiction well enough, but if it's not believable at all, well then I kind of lose interest.
UNLESS it's purposely supposed to be not believable (like for instance I wrote some obvious supernatural erotica and it was quite clear that was the intent...) in which case I'm OK with it.
But I hate to read stuff like "this is a true story..." and then later "after the police arrested her they took her down to the station and every cop fucked her in the holding cell while the chief of police jerked off." Uh, no.
