The only reason I *don't* wear my undies under my bike shorts when I ride to work is because then the undies would be sweaty. So I wear just the shorts, wipe down and pull on undies when I get to work, then pull my bike shorts back up over my undies at the end of the day. Chamois Butt'r is never slimy--always fully absorbed into either me or the chamois!

As a women's health care provider, I would rather use my own bike shorts twice than overclean myself. Our culture is so obsessed with being "clean" that women are taught to over-clean, over-perfume, over-deoderize their vaginas, and it causes no end of misery. Many infections are caused by "feminine cleansing products". Our bodies are self-cleaning in that sense. When we interfere with over cleansing, the "bad" bacteria proliferate, because the "good" bacteria aren't there to control them.
