Lately, I've Been Noticing That About Mid Day And The

Lately, I've been noticing that about mid day and the evening I have this foul smell (similar to my BO) coming from my inner thighs. I know it's not my vagina. I do wear dresses and tend to sweat a lot during the day. I don't have a rash or any redness. I'm thinking it could be fungal or bacterial. I have a prescription for clindamycin (AKA CLEOCIN T) 1 % gel, from treating acne spots. This issue is becoming embarrassing, I shower ever single night, thoroughly wash and dry the area, I feel like it's getting worse. Would clindamycin work for this issue right now?
