Little quirkiness. A few days ago, I might say out of curiosity, I went to consult an important paper encyclopedia of my country published several years ago. Under the heading "prepuce" it was written: "sliding skin covering of the glans which, in the child, covers it entirely. The persistence of this disposition in the adult can cause problems of a medical nature".
I personally think that this text was very badly made and thought out. I guess that might have confused and created various doubts to a young boy, for example in the middle or at the end of puberty, inexperienced on the subject that he read the above. In fact, it is as if it is normal for the glans to be completely covered in the child, while this should be considered abnormal if it occurs in the adult. In short, it almost seems that the norm, after growth and development, is to always have the glans uncovered.
