Human smell is human smell. Offensive smell is rotting body oils skin flakes and dirt. Much like rotting food left out. There was a dramatic drop in disease and death rates when frequent bathing became the norm brought about by indoor plumbing. There was also a drop in disease and death rates when the romans instituted closed sewage passages instead of open trenches to transport sewage away.
However, there are some benefits to generating antibodies by exposing yourself to common bacteria. This enables being able to consume items or be in environments where a non-acclimated person would suffer. But geez. Some people turn showering into some sort of religion. Get dirty and disgusting all you want. Just don't go crazy there either.
In general, keep clean.
But I think a lot of people shower too much and just waste time and water. Besides, the more frequent you shower, the faster you start to smell.
