What've learned the hard way the last time I had prolonged diarrhea is that it's better to wash as soon as possible because having your buttcheeks soaked in stomach acid can irritate the skin even more than the toilet paper. It's no wonder F22 took issue with this as she has vectored thrust and hypersonic missles while M28 doesn't. He's just out of her league, she's gotta dump him and date SU27 instead.
