Crotch BO

Hi! I’m not sure if anyone else experiences this or has any recommendations but my crotch area always smells like body odor. Even directly after a shower. I tried to use anti bacterial bar soap, and have tried many different products but nothing seems to work. I’ve tried feminine wipes and baby wipes, baby powder, I wear cotton / breathable underwear, and shower every 1-2 days. (also this is not an internal issue it only affects the outside area) I worry about putting deodorant in that area due to the aluminum and other toxic chemicals. does anyone have any suggestions on how to fix this? Ty!
