why do we insist on only having one partner when we are not desigined this way only or are we?

unfortunately religion rears its very nasty ugly head on this we are animals simple fact. we act like animals most of the time in our desires and appetites those who wish to control us many time use religion and try to pound their version of the world into out head and force us to comply to their own personal view of what things have to be like however if you deeply love someone you will try never to hurt then and you will also try to keep your raging hormones at a decent level try controlling them not them controlling you and hold on tight as hell to someone special in our life because that is one of the coolest things ever to happen to a human mind and heart expect to get back what you are wiling to give and go for it

I think "are we" is an important part of your question.

I think that, by default, people are designed to have one primary partner at a time, and that partner should have complete say over our sex life. However, there are circumstances that alter our default behavior. Our default behavior is to hurt people who make fun of us, but society teaches us how to be civilized. Our default behavior is to take whatever we want and horde it away, but our parents teach us to share.

Stress, experience, the food we eat, minerals in the water, society, all these things play on us and we act different than our default behavior. Sometimes it's a good thing, sometimes it's not.

I think the hard-wiring for wanting to have only one man is harder wired into a woman than the desire for a man to have only one woman, but I do think this is the default we're all born with before society gets ahold of us. But by the time we're teenagers, that original programming has been so hammered by society as to be almost unrecognizable.

i dont know about being designed that way-everyones different.my husband and i are like weirdly into each other,i doubt that will ever change cause were almost 50 and still worship the ground each other walks on.some people are restless,others more settled-i think it has to do with personality.if everyone were the same,that would be strange-i think theres a wide varietycomplete faithless horndogs,play the field but then get married typesand people like me-who think their partner is a god/godess-and i think also,who u are changes a bit as u age.my wild friends from hi-school who two-timed their dates,they are all calm now.

I believe we are designed to have only one partner.The morals of our society has changed so alot of people think different.I'll say this though.There is nothing better then having someone that u know loves u for u.You can bet your life that they will be there for u no matter what.Plus u are so comfortable with this person that u don't see yourself ever with anyone esle. But this takes time in a relationship and no one wants to invest the time.They would rather hit and run....

Humans, in general, have developed something most animals seem to, but not necessarily, lack: morality. We have created a basic system of morals due to the ideas of right and wrong. This may be due to religion or some other basis but we are still at odds with ourselves. Marriage is a choice to love only one partner, which is a more common emotion in humans than anything else. You are not forced to marry, and can do as you please, at least, in most countries, however, it may not be seen as morally correct in most people's minds.

heh heh polygamy is beneficial to women and a disadvantage to men. All the women in your life will play football with you.

Think seriously. How many families can you afford to maintain? Americans go broke with one family. Look at the bank balance of an average American.

You have to consult the designer who designed you to get the right answer as to what you are designed to do!!!!!

I tend to agree by NATURE we are not meant to be monogamous for life. It's a nice pleasant thought one person for forever the divorce rate clearly SHOWS it don't work that way. I am a jealous person so is my husband but, we go to swing clubs we don't swap we watch we admit we are sexually attracted still to other persons we try to keep in under control. It's unnatural to deny the attraction to others because you are married BUT WE DO HAVE FREE WILL PART OF THAT MEANS you can choose to NOT act on theses urges we are not apes we can choose to stay faithful.

because I was raised to believe that monogamy in a relationship is important.

"Designed" that way assumes you have no control over biological mechanism. When in fact what make us human is we do have control over these instinctual drives.

If your instinctual drives are uncontrolled are you lustful enough to rape, rageful enough to murder, glutenous enough to ruin your health? In all likelihood no. Frankly more then one wife would put me an early grave and not for reasons you might thing. One woman is enough to drive a man crazy, why subject yourself to more than that??

Technically, throughout our lifes, very few of us only have one partner. But through trial and error, we find someone that we can live our life with, and we take advantage of it.

Not everyone is suited for monogamy, though.

Who said we weren't designed that way. That desire that we have in us is supposed to sustain a healthy relationship. But in our culture we are taught to pervert it into self gratification and insatiablness. The desire to have sex is not only for sex. It's for motivation, creativity, and imagination. Just like the desire to eat is not just to be full. It's for nutrition of the body.

I think the mind and the body are sometimes contradicting components, so they need to compromise and get a balance. The rationality of not being selfish seems to make more sense. Immagine if someone you love so much fucks arround, wouldn't that hurt you? So you can now immagine how others would feel if you did to them wat you don't want to be done to you. Love others as you love yourself.
