What a circumcised male does after learning how horrible circumcision is. It works by stretching the skin every day for years, causing penile skin to very slowly grow and form a skin tube with some (but not all) functions of a real foreskin.

However, foreskin restoration still has so many benefits that everyone who does it says it's worth it. You do get some nerve endings back, but not all. Every restorer reports a massive increase in sexual pleasure.
