I think some people feel wired as one or another AND some people choose to live one way or another.
I don't think it is either or.
GG doesn't fall into romantic love with more than one at a time. But he loves me and accepts that means existing in a poly dynamic though he doesn't choose to have multiple partners, because he doesn't romantically love multiple people.
Maca had never considered it prior. But found out after the fact that he can romantically love more than one. But currently doesn't want to pursue it.
I have always loved more than one.
It shouldn't be a problem if you don't.
as long as you get your needs met, that is what matters.
