Hey - reading these views is interesting...
I'll be honest, a guy who shits in my mouth isn't the guy for me.
The reason why some people might be grossly offended by this is pretty simple, I reckon.
Some facts first (well, according to WikiAnswers at least, and in this day and age anything Wiki might be treated with caution.)
Coprophagia, the consumption of feces, can be dangerous for humans. Hepatitis A, Hepatitis B, pneumonia, and influenza vaccinations are generally recommended for those who engage in this practice. Even consuming one's own feces potentially involves risk, as the bowel bacteria and eggs of parasitic worms are not safe to ingest.

And, while we're in this area, how about piss? This from Wikipedia...
Consuming one's own urine (or the urine of a healthy person, if participating in urolagnia involving urophagia) is relatively low in risk.[citation needed] Bacterial infection of the urinating person's urethra, or disease in the person urinating may pose a risk. Elements of medications and dietary supplements can be excreted in urine, which can affect the person consuming the urine. Also, if urine comes into contact with the skin, it can cause a rash in sensitive individuals.
I'm not being judgmental, I'm just stating what appears to be fact - forgive me for that.
And the point I am making?
That no, perhaps we shouldn't be judgmental about other people's fetishes, we do, after all, live in a relatively free world (if you're reading this you do), but where do you draw the line, and who has the right or the power to draw that line?
For example, paedophilia is considered abhorrent by the majority, but who is anyone to say we should judge those who practice it if, like scat, it's bracketed "a sexual fetish".
Killing someone after sex might be seen as the ultimate "fetish", but again, given the arguments of some on this forum, who are we to judge?
Everyone's entitled to an opinion - however, those who're suggesting people who find scat disgusting and shouldn't be so judgmental are, in fact.... being judgmental.
For me, gay sex is pretty weird, based on our species' inbuilt need to replicate itself, but as a gay bloke, I'm kind of stuck with it.
Plus the fact I actually like a nice cock.
