I believe you are all on the right track. Stay away from deodorant soaps. Use Dove, the white, plain bar. I do medical transcript
ion and have some ob/gyn accounts and that is what is routinely recommended for redness in that area, unless of course, there is some other medical issue going on. But if it is simply from soap, switch to Dove. Not my recommendation, just what I've listened to. Oh, and also cotton undies!
