<s>[INST] my husband is having a problem with his penis. It seem like a bladder infection but he has been to the uriologist and he scoped the bladder and he said there is no infection. My husband says that it feels like the head of his penis spasms. He is 67 years old and had his prostate removed 13 years ago. Can you think of any reason for this constant problem?
