Love at least, romantic love--is never limitless. It must always necessarily be bounded by time and energy and resources. There are six billion people on the planet, and it is simply impossible, for both emotional and practical reasons, to form meaningful relationships with all of them! For that matter, I've never met anyone who can manage sixty, or indeed even ten. Love may be limitless in the abstract, but in the concrete world of work and conflicting schedules and finite resources, it's limited indeed. Put simply, there is a finite boundary on the number of people one can love, and spend time with, and a finite boundary on the emotional resources available to anybody. In a nut shell- We believe that love in it's purest form is that of a small child. If you think about it; a small child loves everyone that treats them well until society teaches them who to love and how "Many to love".
Poly people are kinky
Polyamory is a relationship style
It's not a sexual practice. There's no relationship between Polyamory and weird, kinky sex; many people who are kinky are monogamous, and many people who are not monogamous prefer only conventional sex. Being polyamorous does not even necessarily imply group sex! A person who has more than one sexual partner does not necessarily have sex with all of them at the same time.
