It seems that for the most part, women's restrooms are much less messed up than where the men go. Where there is only one or two private restrooms, they are less messy. The conclusion is that men are more restrained and polite about their messes when sharing with women. Just my experience, no actual wider data. I could be generally wrong.
However, in the old SANS group, there was a motion to request that men pee sitting down, generated by the females, for obvious reasons and given strength since some of the women were hosting events in their homes. It seems that older guys drip longer and shake more. The request, which was presented to be an actual rule, was discussed. How would anyone know about cheating, and some men took it as a snip at their masculinity to have to sit down "like a girl."
Toilet issues do create many and varied opinions.
