It's not a skidmark unless it's fecal matter

...and besides, discharges are acidic in nature, having an antibacterial, cleansing effect, so they're *hardly* dirty... but I'm getting distracted from my point.

I'm seeing everything from 1 use only to 2+ uses...

I'm wondering if one of the major variables here might be the presence (and amount of) natural discharge etc?
I know the saying goes "If you have to say TMI, just shut up." but I'm going to say "Probably TMI" anyway.... (as if it matters. You ladies taught me how to use a Diva cup!)
I find that even after a short ride, maybe from the saddle or something, dunno, not going into it, but there's a lot of discharge. It's more of a concern for me than sweat... b/c I have no problem re-wearing sweaty items.

It's that that has me just rolling up a pair of cheap, wicking underwear real tiny and throwing it in my commuter bag as an 'extra' and wearing another pair to work under the shorts. I only have one pair, though I'm looking into the cheaper nashbar ones, too. Wicking undies can go into the shower with me and get washed/rinsed (Dr. Bronners liquid soap) wrung out and tucked into my jersey to dry until I go home.
