Well, polyamory, aka polygamy, can lead to unfair treatment among members of the orgyclan when the main ruler is focused on only one.
Not only that, but some other people think they can just invite a minor into the polycule because they all have wacky age differences.
Sure it's uncommon but it happens fairly a bit too much.
Not just that, but adultery can lead to spread of many stds at once. Condoms slide off easy during an orgy.
And if you refuse to accept my points you are only proving my other point which is that yall simply don't listen
