Overall, Tickler Dual Ring Cock Ring is a great tool to use. It's perfect for both beginners and hardcore users. I would say if you are above average size, you should NOT use it, because it is perfectly snug for us average-sized guys. The ring did get worn out after multiple uses, and the snug fit did wear out.
This is definitely something that we will use again together and my husband has used it while masturbating a few times. Maybe different positions will keep things from feeling like they are slipping around. Overall, we were both happy with it.
