Whaim, if you are having an intense burning sensation then the silicone ring must be too tight!
You can remove coils from the Corkscrew for a smaller/lighter coil that is easier to put on and wear for longer periods of time in comfort. You can also tighten the coils along the entire shaft to help distribute the load and a more secure fit.
This is the set-up I wear for 8 hours or more before fatigue sets in and I need to take a rest.
I am only using a few twists to tighten the coils directly behind the glans here as you can see the space behind the coils along the length of the shaft.
