Haha, there's no such thing as political correctness on this board.
I think it's a great topic to be raised and I agree with you.
It's one thing when both partners have the option to be with others but perhaps one partner chooses not to or has no desire to. There are many couples that I know of where the guy is really into seeing his wife with other guys and/or girls and rarely if ever gets involved in the fun himself. He's just more into watching. And that's cool, he still has the option to join if he wants to.
But when it's a matter of insecurities or jealousy that is keeping him (or her) from being able to be involved it's another story. Swinging is no place for insecurities.
