I find it interesting that, when Master has sexual relations with someone else, I'm only jealous if it's not a friend of mine. When he had sex with Spot - even though he ask/inform me before it happened - I felt no jealousy whatsoever. It was weird, because I tried to feel jealous (it seemed like I should have) but I just couldn't. On the other hand, when he started hanging out and cuddling with a girl on campus I didn't know too well, the jealousy almost ate me up.
Very strange. I wonder if many other nonmonogamous people feel the same way.
