Losing an erection during sex is an extremely common symptom of erectile dysfunction, or ED.

Many people associate ED with men who are totally unable to get an erection, even when they’re aroused. In reality, ED can vary in severity. While men with severe ED may not be able to get an erection at all, it’s also quite common to get and lose an erection.

Just like more severe forms of ED, losing an erection during sex can occur for a large variety of reasons, some psychological and others physical.
