Many odors in the groin can be a normal product of your sweat glands in the genital area. However, a new or different odor can represent an infection. In males, a yeast infection is more common than a bacterial infection. Using an anti-fungal powder in the area can help prevent yeast infections and moistness in the area from recurring.
If you have any itching, burning when you urinate, rashes, or fever you should see your health care provider. It’s always a good idea to see a health care provider and get STI testing regularly if you’ve ever been sexually active.
