Hi- just wanted to get my 2 cents in!

I too used to wear undies with my shorts.
Finally - after much chafing and discomfort, I decided to go commando- and now I wouldn't go back! It is MUCH more comfortable!
and- I know I had great concerns about- what if I crash? Won't that skimpy little piece of lycra/spandex just disintegrate leaving me all nekkid and em- bare- assed???

well- I found out when I endo-ed.
Skidded on the tops of my thighs on gravelly ground-
not a tear! only a teeny tiny"melted" looking mark on one knee.
I am a believer!

huzzah!
and yes - it is very liberating!
