well, a song of ice and fire series has some sex scenes and stuff, but I don't consider it porn, if it is diliberatly sexual and like constant sex, then yes, its a porn book.
...how would one write a work of fiction that addresses sexual issues and sexuality (two subjects that are certainly worthy of address) without having it be porn?
I am not yet born, console me.
I fear that the human race may with tall walls wall me,
with strong drugs dope me, with wise lies lure me,
on black racks rack me, in blood-baths roll me.
