Yes, that does seem true in my experience. I once had to end a social experiment to see how long it would take my ex to take it upon himself to clean the bathroom. Pretty gross. (And perhaps a bit passive aggressive on my part - but I was fed up). If I asked and he did it, it was usually just a quick job, incomplete.So true. And yet all the fuss about public spaces. Some hospitals are starting to have mixed gender rooms ... let's catch up with our thinking!
On the other hand it is likely not true of every male - just in my experience they have not been raised to pay attention to bathroom hygiene as much as women.
