I was going to ask you about that in your progress thead…My balls tend to stick to the tube after half an hour to an hour, and then it gets painful. Most lubes don’t “wet” the plastic of the tube, and they dry out or are absorbed by the skin, leaving spots that don’t slide.
I’ve been sticking with water-base or organic oil lubes for easier cleanup, but I did experiment with vaseline, which surprisingly didn’t do any better than the water-base lubes.
Plain old glycerine lets everything slide indefinitely, but I can’t wipe it completely off my hands, and even a damp washcloth isn’t enough to get it off. Makes it hard to write notes or use the tablet after that.
Silicone lube never dries out, so it’s good for balls in tubes. No lube problems there - just cost.
The secret to cleaning silicone lube (and maybe glycerine?) is to lather your hands or other body parts with liquid soap while dry. Next, enter the already-running stream of warm or hot water and wash off.
