Simples, it is biology.
The younger the male, the greater the biological need to empty one's loin. Ever heard of 'Blue Balls'? Cadaan term for enlarged testicles caused by the retention of semen. This is also why the 'NoFap' challenge is a test of discipline for younger males. After weeks of no Sex or masturbation, we start to become starved Lions in the Serengeti that salivate at the site of a lone deer.
In order for the species to propagate, males are biologically programmed to spread their fertiliser as often as possible when younger. As we age, we are better able to control the urge to hump females simply due to a decrease in libido associated with lower sperm production. This does not necessarily stop some of us from growing into 'Dirty Ol' Men' as the base instinct to hump a female in the prime of her reproductive health is still there. Hence, why many so called 'Adeeros' and 'Aptis' are shacking up with much younger FOB Xalimos in the Vaterland instead of sticking to the one wife that they have already mercilessly bred. Also, this is why you see Cadaan middle aged men in traffic metaphorically licking their lips when an attractive early 20's female etc. stops traffic.
As referenced in The Republic, the male libido can be quite a tough master in youth.
'I may mention Sophocles the poet, who was once asked in my presence, ‘How do you feel about love, Sophocles? are you still capable of it?’ to which he replied, ‘Hush! if you please: to my great delight I have escaped from it, and feel as if I had escaped from a frantic and savage master.’ I thought then, as I do now, that he spoke wisely. For unquestionably old age brings us profound repose and freedom from this and other passions'
