The idea of having an open relationship may seem fun, but you also have to be comfortable with your loved one having sexual relationships with other people. And that, I believe would be the hardest part.I know I couldn't do it, so if I felt there was something I wasn't getting out of my relationship, I would probably just talk to my significant other or break it off, if i felt it was that much of a lost cause. That being said, I also know other people have had a great deal of success with them. So I really think it depends solely on the individual.
