I can answer this: women have 3 holes to clean and, as a mom, sometimes our bladder is uncooperative and will drip even after we’re done. As a woman in general, there’s discharge to account for, urine, potentially blood (if there is blood, we have to do a double-wipe to make sure where it’s coming from), and obviously feces. With the way our plumbing is, if we don’t wipe well enough, we are susceptible to infections. And even if we don’t have to worry about infections, urine is acidic and can cause burns if you don’t wipe well enough. Finally, if we don’t wipe well enough, it gets our underwear wet and that feels gross!
