anybody tried putting a layer of petroleum jelly on the glans when covering with a condom?
I think wearing your own skin over the glans (as with a silicone retaining cone) is going to give the most natural outcome.
I wish I could do foreskin restoration but I have a dorsal slit and there’s hardly anything to pull at the base where my foreskin was slit open. Surgery could be an option but it’s too costly and complicated.
A dorsal slit can sometimes be re-fashioned into the original configuration. Not trivial for sure.
You should contact some restoration device makers who might be able to rig something to pull on your skin effectively.
