Well it is like Cornellian said, men like being in the center of attention. Feel that his wife or girl would fight for him if she felt that someone else is trying to threaten her throne. It depends on the partner sometimes herself, some will be just fine with that while the others won't. I never experienced something like that before, but I won't be enjoying watching this action movie.

I won't get my coke and popcorn to watch my girl and the other one kicking each other, grabbing each other hair and scratching each other face like the cats. Some will enjoy this, but I won't .. it is enough to know that she love me and care about it me. Putting her for such a test would be meaningless.
