Is this SAFE?
I have made a homemade stretching aid and i need to know if it is safe.
I have a crude bitmap I drew to help with the explination. Basically, I wrap
a cloth around my penis behind the glans and cover it with this plastic core from some duct tape. The plastic core has been cut vertically, and small holes have been cut for string to be tied to. After the plastic core is on I use a cable clamp, the kind that adjust the tightness with the little one slot screw, over the the plastic core to tighten everything up really well. After it is tightened i pull the strings for a really good stretch. I have noticed that the tip of my head becomes very red and swells a little after this exercise
(I only do this for 10 minutes), but it is not sore or weird looking the next day.
So, my question is could this cause any nerve damage to my glans?
