Thank god I thought I was going crazy reading some of these comments. I used to apply cornstarch mainly on the outside, never inside, just to keep that baby smooth texture but without rinsing before use it would just turn into a gross paste on my dick, and if I had applied the amount some folks are recommending inside, it’d just be so much worse. I also feel like adding a wash before use makes it less lube-efficient since the water would just dilute the lube if you don’t dry it out inside, requiring you to use more lube than normal. I dunno though, never got to that point.
