If my arteries and nerves, corpus cavernosum work very well in Doppler so where is the issue. Please don't tell me that I am overthinking and physiological because I am doing proper exercise and my diet is very good from the past one year. I am also do kegal as well Now is there any test we will need to do or I need to wait for more time to recover
