You took too much. You didn't leave me with enough skin to cover my penile shaft. The result was that my earliest memories of experiencing erections as a child are memories of severe, prolonged pain. By the time I reached adolescence, the lack of skin caused my penis to develop a sharp bend, which I would later find would make intercourse very difficult. At some point my scrotal and pubic skin compensated for the lack of penile shaft skin. The result is that I now grow thick pubic hair all the way up to the scar you left me.
