currently restoring my foreskin (using chris's air device) and have seen substantial improvement  in sensitivity, skin growth, and my mental state over the past several months. it won't bring back the ridged  band or frenulum obviously, but it is a lot better than nothing. apparently a fully restored foreskin  has about 80% the functionality/ sensitivity of a natural foreskin. it's legit and easy.  restoring your foreskin is one of the most anti-semetic things you can do.
