Foreskin is natural and comes in many shapes and sizes
Thankfully I was born in the Netherlands and it was not the custom to have boys circumcised at birth. Foreskin comes in all lengths, with various degrees of coverage of the glans, and in some cases well beyond. This may be something to keep in mind for those who seek to reclaim their foreskin and assess their progress on the coverage scale. Don't feel that achieving halfway up the scale is a failure, there are plenty of men whose foreskin is naturally only that big.
Yes there is a lot of different amount of foreskin and there is different in cocks. I've come across a few tumblr blogs of uncut penis which was very interesting to see the differences there are, which is every since cock is unique and there seldom is the same in another guy, similar yes but never the same.
