There is a big difference between what you'd do and what you fantasize about...thats what makes it fantasy. There are so many things that I think people would actually do and what they fantasize about doing but would never actually do.

I'm the same way, stories of incest and even beastiality (I know, the two things I'm not supposed to talk about here) turn me on. But I would NEVER act upon either of these things.

I'll have to admit though, poopoo doesn't turn me on in ANY way still.
