It starts to sound almost mechanical.
When someone begins monitoring these indicators during sex, sexual performance anxiety — anxiety about whether one is performing “successfully” in a sexual situation — can take over. Instead of staying with sensation, some attention moves toward checking: “Will it work?”, “Did my partner notice?”, “What happens if I lose my erection now?”
Research associates this kind of anxiety with greater sexual distress and lower sexual satisfaction. Importantly, that is an association: anxiety may make sexual experiences harder, while existing sexual difficulties can also increase anxiety.
The stereotype that “men always want sex” adds another metric to the dashboard. It is no longer enough to “function” correctly — desire itself also has to appear reliably.
That is a heavy set of expectations for a process that depends so much on being able to stop monitoring yourself.
A persistent change in libido can sometimes be worth discussing with a doctor or examining in the context of the relationship. But one refusal, one difficult period or a lower frequency of desire does not make a man defective.
Sometimes one of the healthiest things a man can say sexually is simply “I don’t want to tonight.” And one of the healthiest things a partner can do is not turn those words into a verdict on their own attractiveness.
