Let me introduce you to panoxyl, a body wash with benzoyl peroxide, good for washing your armpits and groin if they stink due to bacteria proliferation.
If the smell is yeasty/sour, then it's fungal, go see a doc or a pharmacist, depends on where you're from, get a cheap shampoo with ketokonazole (nizoral is bougie, so get a generic) and use it as a body wash, and also get an anti-fungal cream with clotrimazole to apply it locally.
