Recently, our daughter (17 in June) told my wife and me that she has started dating not 1, but 2 guys. No introductions needed since we already know them; they’ve been close friends of hers for quite some time now. Daughter put it as: why do I have to choose if I like them both and they don’t mind sharing?
I just don’t like it.
You’re arguing a point I didn’t make. I intentionally called out why it felt ‘weird’, ie strange, or unnatural.
You also claim that poly relationships have more instances of pregnancy, trauma, etc. Can you cite that data or studies to support that?
Things feel weird, strange or unnatural because they go against instinctive feelings.
As for why they are more likely to go wrong it is quite simple. Two teenagers are more trouble than one teenager. Especially if they are in competition with each other. Jealousy is a key driver for violence and young men are the demographic generally most violent. These are things that you know subconsciously, as you have most likely experienced them yourself. As for negative experience with men and in particular men seeking sexual contact i think every women will be able to confirm danger and or having experienced abuse themselves. Now you have two rabbit-horny high on testosterone teenagers that have to “share” one teenage girl. This should cause an instinctive negative reaction by every parent.
As for studies which analyzed the situation where one men has multiple women concluded that these relationships negatively affect the women and their children psychologically.

Now this of course is different compared to a situation where one women has multiple men. A situation which seems to be much less prevalent and i couldnt find studies on quickly. As to why they are much less prevalent, this gives reason for even more worry. There is reason to believe them to be less stable and likely end up with violence, where women on average a physically much less stronger than men.
