Ah, a battle of the sexes argument, time for me to weigh in with my usual 'wisdom' and 'logic' -
Pub Toilets - both are equally dirty but in different ways. Drunk men have very bad aim, plus some idiot always stuffs the bog with toilet paper and the bowl overflows and water goes all over the floor. Women on the other hand have a tendency to hover over but not touch the seat, which in turn leads to splatter of their own. There's also the sanitary towel / tampon situation. Plus I've known several women who've gone wizz-wizz in the sink because some cow on a mobile phone wouldn't get out of the stalls.
In the bedroom - women edge out men slightly on this one. Men who go to bed stinky are just ignorant and selfish, they can't smell their own stink and can't wipe their own arses properly. Women have full on biological warfare going on 'down there' - bacterium, periods, hormone imbalances, reactions to medicines, thrush, urine and blood trapped in pubes, the list goes on and on.
In General - about equal, though women are better at covering up smells. An average guy will shower and wash his hair every day whereas women with long tresses will only wash their hair once every few days. Women like to take long baths, but as they're basically swimming in their own filth, the effects are temporary at best. Men do a lot of physical exertion, so they will sweat more. Women who wax and shave will get pimples on their private bits. Men are more likely to fart in public situations, young mothers smell of stale milk and baby vomit and all elderly people just smell 'wrong'.
And that's my blinkered view of the situation.
