My son approaced me saying that he feels he might have a penis disease. I asked him to be specific and he told me that he saw an article online about a mexican man who has a rare disease which caused his penis to grow to 19 inches long. I told him not to worry about it, but he has been insistent that his genital growth is abnormal. He's now telling me that he measured his flaccid length at almost 8 inches long and that it's getting to the point that he's struggling to maintain erections. I somehow doubt the story he read but is it possible he could be experiencing some kind of growth disorder?
