I can say its real
I have watched my wife making love to her BF and seen how happy she is, what I want from my life is happiness. Watching her being happy makes me happy. What do I get out of it, well gee go figure if my wife is happy....... Needless to say there have been many times as well where it has been the other way and my wife is happy for me. Just the other day she said to me you need to be with your GF.
I think people need to get over themselves and every thing else will be fine, what I mean by that is that people who have problems with poly usually are looking at it with why am I not enough, or how come I can't do that for .... And you know the love I have with my wife is different than the love I have with my GF. But I do love them both. I have made it very clear to my wife that I will not leave her so that she is not feeling insecurity.
A true poly person can love more than one. And I for one am very happy with my personal life right now.
