I still encourage full consumption. I normally hover over My toilets 20-30 mins making sure they consume or using other methods of degradation/scent play. One of My toilets said it is excruciating as I enjoy a very long feeding as opposed to a "quick meal." Being physically force fed has almost always ended in regret and a ruined scene. Plus I just don't enjoy seeing My shit being eaten that fast in the scenes that My toilet's were capable of it.

Listening to My toilet's body language and knowing when to up the intensity or tone it down is quite important for My scenes.
