It is unbelievable what people are telling other people and/or their children about foreskins, just because they do like to cut it away for one or another reason, most probably the extra income coming out of it ...
The fact that your glans does not uncover while having an erection is no problem at all. People who are saying that are putting a big lie in your head.
Such people mentioning that the foresking of a 6 or 7-year old is too tight, also pass the fact that the foreskin is still tied to the glans and that the foreskin will loosen by itself from the glans. From the moment that happens, it will be possible to retract the foreskin in most of the cases.
Let's just be honest that it is easy money for the persons doing the circumcisions based upon those 'exams'.
Again, the only reason cutting the foreskin started is for 99% religion ... and we all know which 'good things' religions have brought into this world. That also would mean that, 1000's of years before, humans with long foreskin would have an issue in procreation!? Most of the things nature doesn't need or create issues are disappearing because of evolution. The fact that this was not the case with the foreskin states that it isn't an issue at all having a foreskin and even that it might have a purpose, no matter what's put in our heads by others or by our own believes ...
My foreskin is also long enough to cover my glans while I'm erect and I can say that it isn't an issue at all. During sex, the foreskin will retract completely or will be retracted during the 'game' ... So, no issue at all having a long or longer foreskin!
