I also stopped using soap several years ago. I shower ~3 times a week, and still scrub areas like my armpits but only using water. As confirmed by friends and family, I don't smell. Granted, I've never had much body odor - I can't confirm this would work well if I naturally smelled more after heavy exercise.

I find it plausible that cleaning too much (or with chemicals that alter the microbiome) could be harmful and as such it doesn't seem worth it - following the precautionary principle - unless there were a specific indication to use soap for treating a disease or illness.
