I agree with the dissenters that polyamory is one thing and cuckoldry another, but...they can overlap. From what I've read (not a ton) of Grinch's posts, he and I are poly-cucks. AND WE NEED OUR OWN WEBSITE!! Seriously, I think The Grinch is trying to come to grips with his wife giving her heart to boyfriends, not just her pussy. It can be quite disconcerting when you know that you have no say in whether your wife fux other guys (as we cux all know), and then you add in she falls in love with them, well! These aren't fuck buddies, they're lovers.
I don't feel the angst that Grinch does because my wife's had a FEW long term lovers during our marriage, and has always reassured me that even if she loves him MORE, she loves me BEST; if that makes any sense to you. And I can relate because I know I can love more than just her, also.
So that takes care of the poly, now the cuck. I have always enjoyed my wife's infidelities--more of her long term lovers were from early in our marriage when she cheated than since she's had permission. I was angry/jealous back then; but turned on as hell. Deep down I liked being married to a woman that would risk divorce to satisfy her need for men. Eventually our marriage got more honest and happier, and I encouraged her to take on lovers.
Being in love makes her happy, so I'm all for it for her sake (the loving poly-sharing side); but for me, since they do fall in love, I take the risk of losing her to another man, and that risk thrills me (the cuckold side). I know her leaving will never happen...but it could. And by the way, hearing my wife tell another man how much she loves him is the biggest cuckold thrill there is. Try it sometime.
