The correct answer is
ED is more common in men over age 65, but it can happen at any age. It’s normal for men to have changes in erectile function. This includes taking longer to get an erection. The older you are, the more likely you are to have ED. About 1 in 20 40-year-old men and up to 1 in 4 65-year-old men have ED, the NIDDK says. But it does not happen to every man as he ages.
