Lots of people think that a person can't love more than just one person. Why?
I do love (and I mean love, not like) two boys, and can't see what's wrong. If I love them, then why should I choose one? I love them both at the same way, it's impossibile to choose.
Like, if you like Coca-Cola, why can't you like Pepsi, too?
Obviously, if you're in a poly relationship both of your partners should know about the other one. I don't think this is cheating.
What do you think?
