Likely as not it’s a natural tendency for both sexes, although because we are significantly different from each other, we go about it in different ways.
Males learn early on that some behaviours work in their favor when it comes to attracting females. Extroversion, willingness to accept risk and physical prowess are amongst the characteristics worth cultivating. Of course we’re mostly talking about early on in our adult lives, which means that we’re still teenagers and barely meeting the minimum grown-up requirements, but it continues in albeit muted form until we die.
We’re also talking extremely generally; exceptions are as thick as bamboo, but guys understand that even if you have hidden charms, the more obvious ones – such as those listed above – get you places quicker.
Which gets me to my point. Although we rarely see it this way, we modify and accentuate the stuff we think the other wants. So desperate are (in this case) guys to be attractive, they’ll go way beyond the boundaries of their character and values to be the person they believe will attract (insert female name here).
It’s a semi-conscious/instinctive project. I overheard Hortense mentioning to a friend that she liked guys who rode motorcycles, therefore I must get a motorcycle. Thoughtless and ultimately ridiculous (who knows whether it’s really what she thinks?) we are driven to do almost whatever it takes.
Such is the need to couple.
