I have experienced ED for some time now. I am 69 years old. However, I can sometimes still get an erection, but it doesn t last. Some time ago, my family medicine doctor told me there was a device, much like a tourniquet, that could be tightened around the base of the penis to help maintain the erection. She also told me it could be purchased at a pharmacy, but she never gave me the name of the device. Are you familiar with what she referred to?
