also is that actually true? there are five sphincters in the gi tract from your mouth to the anus: two in the esophagus, one between the stomach and upper intestine, one between upper and lower, and the anal sphincter. any one of those might be closed while you're kissing someone so i think we need some sort of probability assessment of whether there actually is a fully interconnected tube. with ten sphincters (since it's two people) it seems pretty unlikely to be the case most of the time
