PM veterans need some Penimaster help with Rods, Length and Tension

Hi All, I started PEing a few months ago and decided to go ahead and purchase the PeniMaster Device because I had heard some good things about it. When I put on the device it stretches my penis out but I don’t really FEEL the stretch. I can clearly see that it’s stretching though. Sometimes when I connect the Rods to the device, it will cause it to push up into my glans or over them, even though I put the comfort and fastening belt behind the glans.. Is this because I am using to long of a rod length for my penis? Also, when I adjust the tension to Max tension, EVERY marking is still showing but the thread is fully showing and won’t turn anymore. Does anyone know what I’m doing wrong here? Do I need to add rod length, decrease it? Help me out please.
