Open relationships aren't for everyone. That said, it has worked for me and my spouse. But we first had to overcome our insecurities in our relationship (which is the source of jealousy), and this took years. Now we each have FB's, and we each know each other's FBs, and we each really want the other one to have a good fuck. And most of all we are there for each other; we are each other's top priority. In other words, one of the conditions for an open relationship to work is to set your priorities right. So for example, if just when you are about to fuck a hot stud your spouse suddenly starts throwing up, or he just came home after a terrible day at work, or whatever, the spouse is your top priority, period.
