Hello I share your concern. Medicines you are taking might be related to your sexual problem especially minipress or Metoprolol. Minipress may cause painful and prolonged erection and this condition is known as priapism. In my opinion you should consult your doctor for other safer alternatives like diuretic group of drugs like indepamide or thiazide group of drugs. You should do yoga and relaxation exercises with salt and fat restricted diet. complete avoidance of smoking and alcohol consumption if you are in the habit of it. Regular physical exercise and weight reduction if you are obese or overweight, will definitely help you in controlling your blood pressure. Hope I could answer your question, please feel free to ask for follow up question, I will be happy to help you. wishing you good health.
