Is this normal?really embarrassed

This is not something I would really come out with as its really really embarrassing but not sure if I'm the only one?
I take showers practical daily and clean everyday but lately I keep noticing that I can smell down stairs more often and I dunno if everyone else can either but I'm feeling really self conscious about it, it can't be dirty if I wash it all the time?is this normal?what can I do to stop the smell?
