Editor note:  I notice that his spongy chambers - the 2 corpus cavernosa are a little wider on the "after" photos near the glans/head of penis. This is probably why it is easier to pull the foreskin back.  In other words the shaft is wider than the head so it is easier to pull back.  See my other blof on why masturbation can damage the spongy chambers of the penis:  www.uktightforeskin.blogspot.com
