If you have the early morning erections present that's a good thing to note that physically you are fine however due to stress or anxiety or relationship issues or performance pressure you must be loosing erection are any one in your family hypertensive or have blood sugar or cardiovascular disorders? I would ask you to consult a good competent experienced clinical sexologist at the earliest and get medical advice and treatment. You can do an online consult too if you are not comfortable going personally. There are medical portals helping patients connect with patients like practo, cupidcare, healthyalways and Lybrat e, etc
