<s>[INST] My husband has been unable to get an erection for the last month. He says the only thing that seems different is after a bowel movement he has a sensation that he needs to urinate but he will not urinate if he does it is very little. He urinates normally otherwise. What could be wrong. [/INST] Thanks for asking in Chat Doctor forum Any Painful lesions/infections over there can cause temporary sexual dysfunctions.  The symptoms of frequent urination and urgency is mainly suggestive of urinary tract infections and can also be due to prostate problem.  So, please provide your age details and other related symptoms like any burning sensations while passing urine, vomiting, fever etc. for further suggestions.  You can also visit your doctor for urine test.  All the best. </s>
