My husband gets regular exercise but cant over do it because he is an... amputee. If he walks too much he hurts his wounds on his stump. He eats healthy and is not on insulin or on pills but still checks his blood glucose levels everyday he is type 2 diabetic. We are still trying Levitra 20mg but he is still having trouble getting an erection. Right when the pill starts working he masturbates and has an orgasm but does not get erect enough for penetration. It is getting there but it needs to get harder in the head of the penis. Is there anything else anyone would suggest we try besides just the pills? Maybe sex therapy? I look forward to your response. Have a great day.
