Q1: Sir I have never experienced waking up in the morning with an erection since puberty, so whether I am less potent then the person who gets morning erection frequently but I gets full erection during masturbation? Age 27 Q2: sir whether good diet or abstinence or exercise will bring morning erection which I have never experienced? (My total testosterone level is 414 ng/dl and free testosterone level is 10.87 pg/ml, and no diabetes, no cholesterol, no thyroid, serum homocysteine level is normal)
