Girls: I need some womanly help?!?

If they're disposable pads - e.g. commercial pads like Always or organic brands like Cottons - then you wrap them up in toilet paper and put them in the bin, that's why they have sanitary bins next to toilets in public bathrooms. Some girls use disposable scented bags to put their pads into as disposable pads can smell, particularly commercial brands like Always, but you don't really need to use those.
