Personal experiences are up the people involved. I have only dabbled a little a long time ago. It was fun, and was only that.
I cannot say that if I ever find love again I would entertain it. But if the lady I could meet wanted me to join in this type of venture, then perhaps I may.
Either way, unless I'm invited to become a swinger, it has nothing to do with, and I refuse to be offended by the activity.

No, but that's only because I'd always feel mixed loyalty. I don't like that kind of ambiguity.

I was in an open marriage for roughly 5 years. I say was because we are now separated, not due to some blowout fight or betrayal, but because we have simply come to different points in our lives. We are still best friends, and will be best friends for the rest of our lives I would imagine. I don't think I've ever heard of a marriage that ends like that. I am definitely in favor of open relationships. Jealousy is a harmful phenomenon in my opinion, and has more to do with the insecurities of the jealous individual than some wrong that the other person has done. I feel we should be free to love, both emotionally and physically, as many people as we want. All people should be entitled to this right. It is an incredibly liberating way to live your life, not having to worry about the jealousy of others, and being able to show affection and caring for anyone you feel like.

I don't have anything against open relationships, but it's not for me. Different strokes...
