During my Zivildienst (https://en.wikipedia.org/wiki/Zivildienst), I had lots of contact with all kinds of things leaving the human digestive tract. You get used to it surprisingly quickly, as long as you have and endless supply of rubber gloves and disinfectant. OTOH, the revulsion feces inspire in most humans serves a purpose, evolution-wise, so finding a middle ground would be rather difficult.
