Pesky toilet paper problem
It’s so annoying when that happens! That area is really moist so pieces get stuck easily, but if you dry yourself properly it shouldn’t be a problem. Those little pieces are left behind more often if you wipe from front to back, but to keep your girly parts their cleanest that’s the best way to wipe. Bummer! There’s no exact way to stop it from happening, but these two tips should help.
Try a different brand
Lots of brands, like Charmin, say their toilet paper won’t leave little pieces behind, but most of the time it just depends how thick the toilet paper is. Thin paper from public bathrooms is the worst, so when you have to go in a stall, use more paper than you would at home.
Wiping hard or using the same piece multiple times is what gets ya those gross left-behind bits. Take your time, don’t rub too hard and use as much paper as you need to get clean.
