Now children...
I've never heard anyone talk about why we have pubes and I figured it out. See, men have pheromones in their piss, so it's perfectly normal when a little piss dribbles out your wang after you're done bleeding the rat, and this piss dries in your pubes and when you get active (hot), it releases these pheromones that attract the opposite sex; women. Women have the same thing, except they have to squat when they piss, thus proving; men are superior :).
