How Do You Actually Clean Your Butt To Remove Any

How do you actually clean your butt to remove any Odor? (For Women) I shower everyday with a loofah, I use a dove soap bar with warm water and for private part and a wash rag for my butt with the same dove soap bar. Then after all of that I rinse and towel dry. I'm in high school and I'm always hearing comments like "do you smell that?" "I think it's that girl over there", or "that's so nasty", "disgusting". This happens everyday in school and I really don't know what to do anymore. I don't know if I should change my shower routine or tell my doctor about this "odor" so I can get prescribed medicine if it can help. Also during the summer months it's way worse because in the summer I sweat a lot because of the heat.
