Undergarments???

[Eden]

No I'm not ever going to stick my nose in your shorts - not even if invited to. If you honestly think you don't sweat all over your body and that there isn't any bacteria on the skin of your crotch (or that a pair of underwear will stop them migrating on to your shorts), well okie dokie then.

I've never had a yeast infection, uti or other problem like that either, but I know I sweat and that my shorts are not a sterile zone.... No, I don't wash a pair of jeans each time I wear them, but then again I'm not out exercising in them and they don't have what's basically a sponge in the crotch.

No one's asking you to quit what you are doing if it works for you, but for most people it is not particularly good advice. It's kind of like saying that you can hike the appalachian trail in tennis shoes. Yeah people used to do it (we had a back packing book from the 70's and lots of people were wearing their keds...) and maybe some still do and are just fine, but for most people a good pair of hiking boots will make it a much more pleasant experience. Can you get chafing, even with cycling shorts? Sure you can, but with a good pair of shorts you are much less likely to.

Ah - and there's also the myth of the chamois.... its really not for "padding", though in later years it has morphed a bit. The reason to have a chamois is to provide a nice soft, seamless area for all of the bendy bits on your body so that they aren't rubbing against anything that would be irritating - not to pad your sit bones. That is why I say putting a pair of underwear on with a pair of shorts defeats the purpose - you are putting the seams back into something that was expressly designed to be.... seamless....
