Male sensual desire gets tired too: science debunks the myth

A 45-year-old man, married for fifteen years, with a stable sens life, catches himself staring at the ceiling during the act. It is not a relationship crisis: it is biology. The so-called 'Coolidge effect' – the brain's habituation to repetitive stimuli – explains why novelty is a fuel of desire as powerful as testosterone. But there is more.

Routine kills libido, neuroscience says

The term 'Coolidge effect' comes from an experiment with rats: a male copulated to exhaustion with one female, but regained interest when a new one was introduced. In humans it works in a similar way. The repetition of sensual patterns – same time, same place, same practices – reduces the dopaminergic response. It is not a lack of love: it is physiology.

The hormonal factor: from adolescence to 80

Some argue that desire is purely hormonal: the gland that secretes testosterone slows down over the years. A man can go from ejaculating several times a day to feeling no urgency for weeks. It is not a lack of manhood; it is the natural cycle of testosterone, which can remain high from age 12 to 80, but with peaks and valleys.

Real fatigue or boredom: two sides of the same coin

The debate pits those who are never satisfied – 'you never get tired of it' – against those who claim that 'everything gets tiring'. The surprising fact: too much sens in a short period causes physical fatigue and a refractory period that can last hours. But boredom is psychological and is fought with variety, not with rest.

The implicit consensus is that desire is not linear. You can be tired of sens and still want more sens, if the stimulus changes. Neuroscience confirms it; everyday intuition senses it. What no one quite figures out is why society keeps selling men as insatiable sens machines when biology says otherwise.
