I won't say never, cause everything I ever said I'd never do; I did. lol I will say I don't intend to ever write beastiality, necrophilia, mpreg(I really hate those, unless the character who is pregnant is also an alien. That I can buy into.) I can't see writing something involving piss or feces, just can't understand that attraction at all. I'm not downing those who are turned on by it, I just don't get it. I have written child abuse but only when it was central to the plot of the story. I haven't written it as anything meant to arouse. If I write stuff like that or rape I try to make it clear that it's a horrible experience, not something fun and exciting. I write Dukes of Hazzard mostly and mostly Bo/Luke so incest obviously isn't a problem and neither is slash. Ironically enough I have a harder time writing het scenes than slash and I'm a married woman. Go figure. lol. Can't think of anything else I'd have trouble writing, though I'm sure later something will come to me. It usually does.
