I have had many injuries especially at first. Broken blood vessels mostly, and several larger veins. Takes up to 10 days to heal, so it sucks. But it does go away and I have nothing permanent visible. I use tools now mostly, from jelqtools, I believe they work the lower part of the penis more safely than the hands, and this is where most injuries occur. I wrote a blog and it went like this:
Jelq Tools
When you say hands are better than jelq tools I think you are not approaching the situation correctly. Anything that does Something is beneficial when it comes to any form of exercise, because variety is one of the keys to growth. I have used hands and tools for a long time, and do them at the same time. I find hands are best for working the tip, sort of to polish off what the tools do. I find the tools mimic what the hands do, but with much greater force and control. And more deep into the tissue.
I can get to the point of tolerable pain, or the maximum jelq possible, much easier with the tools, with less effort. Again, use the hands to then work the tip, the last two inches or so, to really drive the cells into that area. This, after all, is where you want them to go.
Here is the real advantage of the jelqtools I use: three of them reach halfway down my scrotum, deeply reach an area the hands can’t without difficulty, or not at all. Some of you have seen the jar lifter tool, and this can reach into this area and is valuable for this reason. W
You are now moving cells from an area never reached before, so I believe this is reason enough for use of tools, and second just to add variety if you have been using just your hands for a long time. I would like to hear back from others if they share or refute my opinion that tools are less fatiguing to use and more powerful than hands, at least on the lower part of the penis.
