One survey found that about half of all men in their 60s reported some dissatisfaction with their sexual functioning. But many called the problems "small" or "very small." Meanwhile, according to the National Institutes of Health, 17% of men in the United States between the ages of 60 and 69 have completely lost the ability to have an erection. Which is a big problem for most guys.
Erectile dysfunction is not a natural part of aging. Check in with your doctor if you're over 60 and experiencing problems in the bedroom.
