My odor...i need help?

ok well i am indian and sometimes i worry that i might smell to other people. i do have body odor but whenever i ask people who would tell me honestly, they always say that they can never smell anything off of me and i have a neutral smell...but there is always that constant worry that others might smell my BO. im not sure, but today, in one of my cles, i think some girls were talking about it, but it cldve just been because i was hella paranoid cuz i had been concerned from b4 that she wld get a whiff...advice?
