Hey Jay it is great that you are having such support by your wife.
But I'm a little bit cautious about open relationships or marriages. I just can't see it working somehow. Two people that came together to be with each other has to be extremely honest, easy going and open minded to feel confident when stepping into that direction and allowing third party to be involved. It is sometimes too complex situation with two partners, with more people dynamics could become even more difficult.
I look it like this: there are always some attractive people on our way no matter on gender and marriage status. Why would be different now if you are admitting that there is some attraction to men?
Jude has said nicely, don't waste "pot of gold" that you already have
