Hello I share your concern. Dribbling of urine might be related to prostate disease / inflammation or infection of the urogenital tract. Here, I would advise you for a battery of tests like urine culture and sensitivity test and an ultrasound lower abdomen to rule out urine infection as well as Benign prostate hyperplasia (enlargement). For erectile dysfunction you can take sildenafil group of drugs under medical supervision as this drug may cause side effects like headache and abdominal discomfort. Meanwhile maintain good hygiene, write back to me with your relevant medical history and reports if you have any, so that I will be able to tell you more precisely. Best wishes
