i dont have a thing for scat or anything but its not that big of a deal really, at least its not an ageplay kink or god forbid a gore one
...Ah yes, asking someone to shit on your chest? Completely normal.
I'll agree on age play, though. I mean, if I'm fucking someone, I don't want them acting like a baby (and anyone who does should have their hard-drives checked).
Gore... Not my thing, but not as bad as the other 2 (I find it funny how you say "or god forbid a gore one" as if that's worse than age play).
