Where the anxiety comes from and what the physiology actually says
There is a script handed to men about what their bodies are supposed to do, and it is, on close inspection, a work of fiction. It describes a body that responds on demand, performs to a consistent standard, operates independently of mood, stress, fatigue, or feeling, and treats any deviation as failure. Almost no real body works this way, and the gap between the script and the reality is the engine of an enormous amount of unnecessary suffering.
The central mechanism is a feedback loop, and it is worth describing precisely because understanding it is most of the way to disarming it. Male arousal depends significantly on the parasympathetic nervous system, the branch associated with rest, safety, and the absence of threat. Anxiety activates the opposite branch, the sympathetic system, the one that governs the response to danger. These two systems are, in this context, antagonistic. The body cannot easily mount an arousal response while it is simultaneously preparing to flee from a threat.
Here is where the loop closes. A man who is anxious about performance activates his threat system. The threat system suppresses the very physiological response he is anxious about. The suppression then becomes evidence, in his mind, that his fear was justified, which increases the anxiety, which further activates the threat system. The fear produces the outcome it feared, and the outcome strengthens the fear. The cause and the consequence chase each other.
The cruelty of this loop is that it is self-confirming. It does not require any underlying physical problem to sustain itself. It generates its own proof. A perfectly healthy body can be locked into apparent dysfunction entirely by the anxiety about dysfunction, with no physiological cause beneath it at all.
The expectations feeding the anxiety are, importantly, not drawn from reality. They are drawn from a cultural script and, increasingly, from pornography, which presents a performance standard that is staged, edited, and unrepresentative of how any body actually functions over time. Measuring oneself against it is like measuring one's daily life against an action film. The comparison was never valid, but it operates anyway, quietly, in the background.
The way out of the loop is not more effort, because effort is sympathetic activation, which is the problem. The way out is the removal of the demand. When the performance stops being a test that can be failed, the threat system has nothing to respond to, and the parasympathetic system, which was always capable, is free to operate. The body was rarely the problem. The story about what the body owes was the problem.
