It’s an intimate act, so I guess it would be.

Need two to tango

only if a lil gets in someone's mouth

LOL, no. And cheating is possible with and without sexuality.

Yes if you empty your bowels completely on someone else, that’s especially bad 😂😂 wtf

...I guess it is if it means something to someone. I guess I better make it clear that my partner can shit where she likes (but she better wipe up :o)

Not unless they're into that too.

I think cheating can only be defined by the people in the relationship, but my general rule is, would you do it in front of your partner, or how would they react if they found out?

And again I remember the famous K.i.Z. Skit on "Hahnenkampf" "Kinder, ab in Whirlpool. Ah, sie ist wohl doch noch beim Aerobic. Anscheißen ist ja auch noch ken Fremdgehn. Yeah, Brother." Of course it is cheating. Doing sexual stuff with another person without the knowledge and permission of your partner is no good.
