Dome, I am a felow scientist and agree with your logic. But I have one prblem with it and i speak from personal experience. I have tried to squeeze my muscles to make my shit more areodynamic, but sometimes it besomes curved and comes out rubbing on one side of my asscheeks. It feels like I toook a good shit, but when I wipe I'm like WTF?!?!?! A bunch of shit smear on one ass cheek while the other is as clean and dry as a whitsle. and don't even mention those stray ass hairs that get tangled up and steer the shit away from its natural course. As far s water hitting your ass, it's a tricky one. If the spirits are good to you on that particular day, then you will have those badass shits where you only have to wipe once or twice. Otherwise, you have to use half a fuckin roll to make sure you got all teh skidmakrs off your ass. I usually wet the toilet paper a little with the faucet water and wipe with that so I can be sure that all the shit is gone from my ass when I wipe. One question. have any of you experinced a shit whereyou feel like you have to take a big shit, and as hard as you try to push it out, only pencil thin logs come out? THEN, later on in the evening, you takle one of those massive shits where the shit has petrified inyou rsystem and doesn't have the elasitcity to turn around the bowl, thus creating a log that won't flush?
