about circumcision

I’m not circumcise and I couldn’t. Why? When I’m really hard, there no much skin left.

I’m wondering what will happen if I gain say 1 inch in length? Does the skin grow too?

yes it does.

I have an obvious grow mark (equivalent to my length gains) of lighter skin at the base. Some people complain of too much skin growth but it should shrink back (at least a little). Hangers tend to grow the skin first and the grow the penis to fit, Stretchers/jelquers tend to grow the skin along with everything else :)
