Progress is being made!

I have started retracting fully across the rim throughout while previously I had left my glans half-covered until the end. It takes some effort but it is possible to expose a little more around the back of the head. The oddest thing happens when I tug the skin down though, my body's lube seems to get trapped in the fold and when pulled down it sort of squits out in a bubbly, and oddly satisfying, fashion.

Things seem to be improving towards the top and I am no longer resigned to leaving it how it is.
