Cheating - it's a choice, but we're being programmed and manipulated daily to make the choice to cheat.
Men and women in western societies are all targeted from birth to play their role in our predominately pornified society.
Males are bombarded constantly with messages that they should regard females predominantly only in one way - as providers of sexual arousal.
Females are bombarded constantly with messages that they have no value outside of providing men with opportunities for sexual arousal, primarily visually, so they must focus their attention, money and efforts on making themselves appear as sexually attractive/arousing as possible at all times.
By the time a male is in his mid teens, he is de-sensitised to seeing pornographic images. He believes that 'all men do porn' and that the resulting hypersexuality, is a normal condition. He is also likely suffering from an addiction to porn, perhaps to strip bars and prostitutes too. Men can become so de-sensitised to seeing sexually provocative women on a daily basis that they are no longer aware of the inappropriateness of being sexually aroused outside of an emotionally intimate relationship. Eventually it is common that men will regard all women as sexual providers, only having value based on their appearance. The capacity of a woman to be a true friend, business partner, intelligent being, is not even considered. Within the pornified society, men are not educated to value emotional intimacy with either males or females. Males are instead manipulated to become users of women. Women are regarded as sexual objects to be used by men for sexual purposes. Women are regarded like toys or like a car, or like a sport - to be evaluated on the qualities that will bring the owner/user, the most satisfaction. Females are simply objects or items to be used to provide males primarily with sexual pleasure. Emotionally healthy men don't treat/use woman as sexual providers. They can treat women as whole people.
Women become de-sensitised to being devalued. They are groomed to present themselves as being sexually provocative visually in public. Make-up, short skirts, low necklines, mid-riff revealing tops, super short shorts, high heeled shoes etc all are accessories used by women to increase their sexually enhancing appeal to men. If a man looks admiringly at a sexually provocatively clothed woman, the woman gains a power hit - a dopamine hit - from his visual attention. The male's attention momentarily assures the female that she has some value. An emotionally healthy woman knows she has innate value and does not need affirmations from the gaze of male strangers.
Cheating is a logical, progressive extension of accepting sexually abusive beliefs.
Beliefs produce thoughts. Thoughts produce feelings. Feelings produce actions. Actions produce consequences.
