Commando!?

Tara
Alright ladies. I'm a fan of non restrictive clothing and am prone to uti's with thong/tight workout pants combo. I'd love to go commando all the time; but what's the secret? 
I mean, I'm worried about rando spotting, regular discharge, etc. (I also have copper iud, which is known to increase cerv. mucus, so maybe I'm just the weirdo who overthinks this!?)
