No. It's not because of 8inHg alone. When your epidermal layer start to stress, resultingin edema, it means the skin became too thin from prolong pressure exposure. When you healed up, go from 5inHg and creep straight to 8inHg without staying at 6 or 7. Make sure to only do this about 1 week out, allowing that new skin patch for the edema to fully toughen up.
The cautionary tail is quite valid. This is why I don't encourage vibration and direct high heat application. Low to moderate heat, such as warm to slightly more than warm water, is more than enough during pumping. Why? I'll explain in layman's terms.
Depending on the vibration level, if you're reaching between 30Hz to 44MHz directly skin application, you're creating a collagen destabilizing effects. When your collagen bonds destabilized and you're overstressing it further, destabilization continues to stretch, break, and further destroy your collagen bonds to the point of improper repairs. It's like stressing a puncture hole on your inner tube so much that you can't patch it up. Same goes for the internal tissues. Heat has less damaging effects, but too long of heat exposure can create the same effects. Introducing a breakage once, then stretch, that's not a problem. The bond will reestablish within a few moment to a few hours. Same bond keeps on overstressed, your body will give up on you and ignore the repair. Now, you have a broken bond that will not be restored. Imagine that is your nerve that don't want to be repaired. Your dick is now broken at that specific area.
If you're using 30Hz to 44MHz on the
cylinder, you're stressing the
cylinder wall based on the amount of energy at the frequency being applied. Crack, and pop, under pressure, shards can damage your penis during an implosion.
Ooo..Hulk penis, here you come (fire)
