Civilization, that’s the key. In a civilized society, male human beings are expected to suppress their normal animal instincts regarding sexual behavior with female human beings. This suppression is contrary to normal male animal behavior. Rabbits, dogs, cats, etc. operate sexually in a non-civilized manner. Cavemen acted on basic male animal instinct. Then, over time, they became civilized. While some civilized men have been able to overcome societal sexual restrictions (Hugh Hefner comes to mind), most civilized men just direct their energies toward non-sexual activities and remain frustrated and horny. In regard to understanding female human beings, women: I have no clue.
Hugh Hefner is not civilized
don’t feel bad. not even women understand women.
