'supposed happy marriages'
Since I am young, sexually active and knowing myself I would not marry at this time if ever.
In todays world more than ever in recorded history, women (I am assuming you are a woman) are now able to support themselves which was the main reason for marriage ....To ensure support of women and offsprings.
In many Matrilineal/ matriarchal societies women do not marry exclusive to one man, nor have just one intimate partner....Polyandry is the norm - marriage is often not binding in such a society.
Unlike today in male dominated societies, in which marriage is binding and in biblical times....Polygamy was the norm
Monogamy especially romantic monogamy is relatively new as a social convention
I am enjoying my life and freedom way too much to be encumbered by any one man.
Thats your gonads speaking....but with this freedom comes much responsibility
Due to infidelity I've seen too many supposed happy marriages fall apart over time. If one feels cheating is acceptable then a happy marriage will eventually elude them.
True....but only so because we expect from each more than we are able bear given the tools and techniques we possess. In an effort to create a heaven on earth, some have seek to coerce (political and religious) mankind into Godhood (personal and universal) by hoping to use the tools of fear - guilt, punishment, and repression. To control These most Powerful of Mankind Natural Drives - Energies and Forces..... cannot always or for long be subdued in such manner
It is a mark of spiritual and mental development to be able to direct the animal Drives with in us. For these Animal Energies if Transmuted open the door to what the Ancients refer to as the Magical and Miraculous ...Godlike Powers.
Let us be clear here having sex with some one other than your marriage partner is not in the strictest sense cheating or infidelity. Cheating denotes deception and infidelity connotes unfaithfulness. The essence here is Acceptance, Honesty and Loyalty to that which is agreed upon.
