Sexual dysfunction and ED become more common as you get older. Only about 5% of men age 40 have it. But the number rises to 15% of men age 70. This doesn’t mean growing older is the end of your sex life. Doctors can treat ED no matter your age. Age isn't the only cause. Type 2 diabetes, obesity, smoking, and high blood pressure all make it more likely.

Symptoms of ED include:
Erections that are too soft for sex.
Erections that are don't last long enough for sex.
An inability to get an erection.
If you can't get or keep an erection that lasts long enough or is rigid enough for sex, you have erectile dysfunction.
