Hello there.  I can understand your concern.  Is it his query or is it your query in his name? There is nothing you can do about the size. Size doesnt matter and also there are no size charts available to say what is the normal size and what not. Work with what you have. Size doesn't matter performance matters. Consult a general surgeon in person for further evaluation and management. Best regards. Dr. Anil kumar jain. Bangalore.
