The real cause isnt the ability to get sex like the harpies like to screech back and forth, its the consequences that come with everything. Going out to a brothel or even just offering a chick standing on the side of the street 100 bucks would guarantee a quick fuck, but what isnt so quick are
>stds
>accidental pregnancies
>rape allegations
Any of these will alter or ruin your life so each random woman has a hidden risk and most men know it.
