Haha, when my best friend and I are both crushing on the same guy or have the same celebrity crush, we often jokingly offer to "share" or "take turns. " And there are definitely polyamorous clusters of three or more people that share a closed sexual relationship with each other. I've heard that can be great for certain people, and that those people can be very happy as long as everyone comes in expecting the same thing and they agree not to develop possessive attachments.
But in the majority of cases, I can't imagine it would work all that well unless you grew up with the idea. For example, there have been tons of cultures around the world where polygyny was the standard, often where one woman is publicly declared the "head" or "favorite" wife, and I'm sure those women could be perfectly happy with that arrangement. In the modern western world, though, I think there would be a lot of tension between the two women, simply because most of us have grown up with the idea that a relationship is for two people only.
I'm writing all this under the assumption that all people involved know about all other people. Deception in this case would NOT be cool. And of course, bigamy is usually illegal, and bigamy cases almost always involve deception.
Ok. Nooooooo. Never if he's mine - he is mine - why would I want to share him with someone else. I would never be happy - I would be mortified - I mean having sex with me and then let me turn around - the other one is feeling left out. No I myself don't understand how can women do this to each other.
As a young male, friends of mine would jokingly say "heck yeah". Males generally here within the United States feel that this is not good for marriage, however, without a doubt this would be ideal for one night stands. Trust me. Nobody wants to commit to this three way relationship. Traditionally feels wrong and will likley stay this for for years to come. Don't worry ladies. The male wants to marry one individual. I will marry one person and will try to keep the marriage relationship strong. Wish the divorce rate would go down. Don't marry too young. Live your life with family and friends before you tie some knot. by the way don't let me influence you while everyone is different. This is coming from me while it's my belief.
