Yeah. Happens to the best of us. It got me too a few weeks ago. It happens to the best of the best of us.
Yep. Your skin hasn't been conditioned enough to be under that kind of moist environment. No worries. Allow the skin to aerate over time and it will return to normal and toughen up.
You can perform stretches away and around the blister. For me, when I have a blister on the glans, I don't cause excessive pressure of fluid to build up on the glans. I use wraps, my Theraband, and squeeze as much blood out of the glans as possible during the wrap to prevent fluid from entering into my glans during my stretches. I use LengthMaster a lot, and that can creates tons of fluid pressure on the glans under intense traction force. As long as you can wrap the glans tightly to remove as much blood as you can, you can do the stretches without worries.
Once you have blisters on your glans, back off, and allow the glans to take care of the blister first before continuing. Otherwise, you'll get a larger, bloodier blister.
Hehehehehe. Wait unti you see a 1in to 1.5in increase in size without any blisters or fluid retention. Forget being hooked. You'll be dazzled to the point that you cannot allow PE to leave your life.
inHG stands for in of mecury. You also see mmHg, which is a millimeter of mercury. mmHg is much more accurate when it comes to medical monitoring, or for precise mechanic pressure adjustment. But we are dealing with an expandable penis. We'll go insane using mmHg. We use inHg instead.
