One thing I'll say about men being piggy: when compared to women they're rather unclean. Or at least I assume that this is so.
I'm basing this assertion off of the fact that every guy's shower that I've ever seen is equipped only with a bar of soap, and a bottle of shampoo. Women's showers, however are filled with so many innumerable chemicals, strange sponge like devices, potions and balms, that it makes my head spin. I assume that the end result of all of these strange fluids and contraptions is to be generally cleaner and better smelling, but judging by the sheer number of them I'd say that none are likely as effective in and of themselves as good ol' bar of soap and shampoo.
