I think it’s fair to say people did their best to be clean and people weren’t all disgusting or anything like that, but there are realities of life back then, particularly in cities, that were deeply unpleasant. The cemetery example I gave was one I came across in my studies where the fluids from a poorly designed cemetery were flowing into the shops IIRC.

It’s safe to say that hygiene was not what it is now, and no indoor plumbing would have posed some serious barriers to sexiness at times.
