I was wondering if I should have lost my frenulum on my penis? Because I have heard that boys normally do so should I have lost my frenulum?
The frenulum is the folds of skin under the glans at the end of the penis, on the bottom side. Its purpose is to be the point of attachment for the skin of your penis. This loose attachment is what allows the penis to change size without over stretching the skin. It also is the point where the foreskin is pulled down during an erection so that the glans is exposed. So, no, it doesn't go away. Every male has it.
