I always ask for experience. I provide a warning every single time a toilet requests forced consumption. Every first time toilet with forced has had a "ruined" scene. My toilets describe the scene and their boundaries. I accommodate, even if they choose forced after the warning. Generally though, when I listen to the body language and adjust the intensity accordingly, the scene ends up being phenomenal.

No one has actually genuinely cried from over stimulation. The tears are more similar to like when you eat incredibly spicy food.
