wounds that prevent him from doing much exercise. The doctor does not want to prescribe testestorne medicine but gives him 20mg of Levitra. It works a little but not enough for a complete erection. Does anyone know what we can try to help him achieve and maintain erection? I believe his prescription drugs are part of the problem too. What can he do to counteract the side effects of these drugs so he can get an erection? Thank you for your help.
