I had this also. Take baths. They truly help and try Hibiclens as a wash. This is what I learned. Anything that makes you sweat will make you break out. After a workout wash with hibiclens. If you walk for hibiclens when you get home. Hibiclens will be your best friend. I believe some of it may also come from wearing G strings. If you don't have one that separated your butt cheeks rub. At least that is partly my case. Also baths with some epsom salt help tremendously. Good luck. Once you get it under control and keep washing it and the bacteria goes away it doesn't break out near as bad.
