OK look this whole line of loving your kids or both mom and dad or sister Sue and cousin Mike is about to make be heave. As human beings, unless we have some serious wiring flaws, we are all capable of loving more than one person. But give me a break here, the poly life style is about having sex with more that one person…guilt free. Now PLASE don’t get me wrong, if that’s your thing and you can make it work with all the people you are being intimate with MORE POWER TO YOU. But to compare a lifestyle choice to loving friendships or familial relationships is missing the point of the thread, and in all likelihood justifying your choices cast onto another person who at some level doesn't feel the same way.
