Lube and Lotion Types

I use a phallosan ( I can’t post in the extender forum yet) and with it comes the suction bell. I use Shea lotion on the sleeve in order to make a better seal and prevent snagging and pinching.

So..

What other types can you use in order to leave on for prolonged periods that might even have medicinal benefits?

Ever have issues with skin too moisturized or wet?
