Went to the dermatologist yesterday. I do have some type of fungal infection. Taking some potent durgs to knock it out. Asked her why. She said hot wet dark area. Ideal growth area. I asked was it caused by not washing my shorts enough and was told probay not. Probally what happened I chaffed and never let it heal completely. I received my aero tech pro shorts. There is no chamois in the sit bones area. Don't know if I care for that. Bill
