I am concerned about my husband. He has gained a lot of weight. He has difficulty going to the bathroom. He sits and when he gets up if he doesn't run he will wet himself. He says the stream is week and sprays different directions. With the weight gain he has developed a belly button hernia. His penis is almost inverted sucking inward. He will not go see about it. It seems like to me his sack is enlarged, but he says it is cause he is fat. Should he get to the doctor?
