Upper age doesn't reduce the sex drive or erotic desire for us older guys, but aging may affect one's ability to get it up and keep it up. At 73 years I still have a great libido and function well manually or with a partner. Almost every morning I wake up with a firm erection, and experience them during the day too. However, they don't last long, and I use viagra to boost the blood supply to my penis, so it will last for an hour of good sex. I watch my diet and work out daily at a gym, where my package gets a lot of attention in the shower room. That gives me a lift too. I've never smoked, which my urologist says benefits me. Guys should be selective with the food they eat, and exercise for good body health. According to my doc, smoking and cholesterol are a sure way to lose your erectile ability earlier than normal.
