Dr. Anne Truong explains how to distinguish psychological from physical erectile dysfunction using symptom patterns. If you're under 40 with sudden problems only during sex but normal morning erections, it's likely stress or anxiety. If morning erections disappear and the decline is gradual across all situations, physical causes like vascular issues or hormonal problems are more likely.

Now, I wanna clarify an important distinction. Not all ED is identical, and the pattern recognition is where it clinically matters. If you're a younger man, younger meaning less than 40, and experience a sudden onset of difficulty strictly with a partner, but still wake up with morning erection, has zero issues when alone, that strongly points towards more of psychogenic response, such as stress, anxiety, performance anxiety. However, when morning arousal disappears across the board and the decline is generalized and gradual, the probability shifts towards more of physical causes such as poor blood flow, more hormones, and sleep disruption.
