Also, wearing undies under the shorts doesn't allow for the "normal" ventilation or "wicking" of sweat that occurs sans undies. The discharge washes out, and if a little discoloration remains, well... consider it "fading". Assuming the shorts are clean when you put them on,, they won't present a health hazard.

I would also check your saddle adjustment/saddle choice. If it's correct, you shouldn't be getting that friction buildup that causes the iritation.
