[Stingy Jack]

Well, I hope you took note of my stipulation above. "Just as long as all parties involved are emotionally stable enough to accept and co-exist in such a situation." I'm pretty sure most people aren't. Because (also an instinctual thing), we don't like to share. :D We are very territorial creatures who are highly aggressive and protective when it comes to keeping our stuff to ourselves (and I hate to label spouses as "stuff" here, but we're even more protective of them than we are our material things. I've gotten into fights with really close friends before because they thought I was getting too friendly with their current girlfriends.)
