Foreskin is pretty amazing stuff.

I made the comparisons on the right to try to get an idea what the difference in surface area is between when I'm soft and when I'm hard.

Subtracting the length of the glans (1.25"), I found that the skin was almost triple the surface area (259%) during an erection. I had started to experiment with foreskin restoration before I got

33 square inches - almost three times the surface area!

onto penis enlargement, and one of my frustrations was that I was so short that taping was very weird - it turned my penis into just a little stub. Now that I've got over an inch more to play with, the process is a lot easier.

But this does raise an interesting question, because despite the amazing amount the foreskin can stretch, it can only stretch so far. If you are very tightly circumcised, so that your skin is pulled completely taut during an erection, could it be that stretching your foreskin would allow your erection to naturally become longer?
